Explore geometry basics with six lessons on points, lines, planes, linear measure, points between line segments, midpoints, the distance formula, and practice through videos, quizzes, and varied problems.
Define points, lines, and planes; name lines with two points or planes with three points or a cursive letter; explain colinear, and distinguish line, ray, line segment, and intersections.
Learn how to measure line segments with English and metric units, define precision as the measurement's uncertainty, and compare precision versus accuracy through examples and scales.
Explore points between line segment endpoints, learn how partial lengths add to the whole, identify midpoints, and solve for unknown segments using algebra with examples like AB and BC.
Identify midpoints by dividing a line segment into two congruent halves. Explore midpoint problems, algebraic solutions, and the midpoint formula on the coordinate plane.
Apply the Pythagorean theorem to right triangles, using a^2 + b^2 = c^2 to find the hypotenuse or missing legs.
Master the distance formula on the coordinate plane by using x1, y1, x2, y2 and the Pythagorean theorem to find the distance (the hypotenuse) between points in units.
This unit is the second in a High School Geometry curriculum. It teaches basic geometric concepts so that they can be applied to more difficult concepts later on. It can be taken by traditional high school students as well as High School Equivalency (HSE) students who are learning about geometric topics for their equivalency exams (GED, TASC, and/or HiSET).Topics include:
(1) Points, Lines, and Planes
(2) Linear Measure and Precision
(3) Points Between Line Segments
(4) The Midpoint
(5) The Pythagorean Theorem
(6) The Distance Formula
Each section has a related video, a video quiz, and a section quiz. The video quiz is to be taken along with or shortly after watching the video. The section quiz is to be taken after. To supplement the course, you can use any textbook.
This course should take approximately five to ten hours to complete.
