A complete reference guide to points, lines, and planes. It provides definitions and interactive activities that enhance further explanation.

A comprehensive guide for learning all about perpendicular lines with definitions, how to draw them, solved examples, and practice questions

Students can review basic geometric terms using these self-check, multiple choice questions. Three levels of questions are provided.

Brush up on your math skills relating to parallel and perpendicular lines then try some practice problems to test your understanding.

This lesson explains what are parallel and perpendicular lines and includes varied exercises and a video that shows how to draw a perpendicular line and a rectangle using a protractor or a triangular ruler.

Find the gradient, equations and intersections of medians, altitudes and perpendicular bisectors using our knowledge of the mid-point as well as parallel and perpendicular lines.

In this task, students are shown three unit squares and two line segments connecting two pairs of vertices. They are asked to find the area of a triangle formed by intersecting lines. They can solve it using coordinate geometry or...
