An introduction and an insight into how we learn5:59
Welcome to our course on understanding angles. I'll briefly share a personal story—I once struggled with Algebra in school until my dad patiently helped me see it differently. That experience taught me that we all learn uniquely and sometimes, the issue is how something is explained.

I've spent over 20 years exploring different learning styles and educational settings, focusing on neurodiversity like dyslexia, autism, ADHD, etc. One key insight is that varied activities—worksheets, games, posters—create multiple memories which aid recall during tests or class discussions.

This course aims to build confidence through enjoyable and relevant learning experiences. As you participate more and practice regularly, your confidence will grow alongside your skills in a positive cycle.

The content here draws from two decades of my teaching methods refined by feedback to ensure clarity. We’ll use diverse resources throughout the course designed for easy understanding and boosting your confidence in previously challenging areas.

Enjoy the journey as we make angles less intimidating and hopefully fun!
Angle Facts14:36
In this section we will look at angles facts.

Here’s a concise breakdown of what you need to know:

1. **Angles on a Straight Line**: Remember that any angles forming along a straight line will sum up to 180 degrees—a handy piece of knowledge when calculating missing measurements.

2. **Right Angles**: The quintessential right angle forms the basis of standard corners and measures precisely 90 degrees—indispensable in construction and design.

3. **Angles at a Point**: Envision turning completely around; the total journey encompasses 360 degrees, which can be dissected into smaller angular slices based on surrounding geometry.

4. **Parallel Lines and Angles**:
- Look out for Z-shaped patterns indicating alternate angles between parallel lines—they're equal.
- F-shaped configurations signal corresponding angles that also match each other.
- C-shaped cues help identify interior angles that together equate to 180 degrees when they’re on the same side of a transversal cutting across parallels.

You will also find 3 resources attached that you can use to help you familiarise yourself further with the basic angle facts
Triangles8:23
In this unit we'll take a look at the 3 different types of triangles:

**Triangles**:
- No matter how diverse their sides are, triangles always boast an internal angle sum of 180 degrees.
- From scalene varieties with unique sides and angles through isosceles with its pairings up to equilateral types sporting uniformity throughout (60-degree angles), triangles offer geometric diversity grounded by constant principles.

Once again, you will find the 3 resources to help you solidify your understanding. Enjoy
Sum of the interior angles3:30
In this section we will look at the basic formula that you will need to calculate the sum of the interior angles (which basically means; what all the angles inside the shape add up to).
If you need to establish what 1 of those angles is, simply divide the total angles by the number of sides.
Exterior angles in a shape3:35
In this final video we'll look at how to calculate the exterior angles in a shape, which is simply:
360 divided by the number of sides
This formula would give me one exterior angle.

From here you can also work out the number of sides.
360 divided by 1 exterior angle = number of sides

In this video we'll also use this information to work out the size of 1 interior angle.

Description

I remember as a child sitting in a GCSE maths class and the teacher was explaining something to us. I had no idea what she was talking about and, unfortunately, she chose me to answer her question.

I sat and looked at her blankly before giving her an answer with only the slightest glimmer of hope that it might be right.

No chance. She explained it again using the exact same words. She asked me again for the answer, but I was none the wiser. She might as well have been talking in a foreign language. I had no clue.

With a roll of her eyes, she explained it for the third time in the exact the same way. I still had no idea what she was on about. But, now with a bright red face and a fear that the tears I could feel welling up inside would escape down my cheeks, she gave up. I felt like a complete fool in front of the whole class.

That night I sat with my dad who used completely different wording and I got it. It was simple. He wasn’t a teacher; he just had the patience to explain it to me in a way that I understood. That has stayed with me for a long, long time.

Many of the explanations that I have used here are based on the experiences I have encountered over the past 20+ years with my own children, through my degree and the other students like you that I have worked with as a tutor.

In the first section we will look at how we learn. Then from here we will dive into the basic angles facts, types of triangles, and how to calculate the sum of the interior angles in a shape, and the interior and exterior angles in a shape.

Hopefully by the end of the course any questions you had will have been answered.

After each video you will also find 3 resources to help you practice what you have just learned in the video.
