Lesson Plan: Altitudes of Triangles Mathematics

Start Practising

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to draw, define, and solve problems involving altitudes of triangles.

Objectives

Students will be able to

define the altitudes of triangles,
draw altitudes of triangles,
identify the characteristics of the altitudes of different types of triangles,
solve problems involving altitudes of triangles.

Prerequisites

Students should already be familiar with

right, obtuse, and acute triangles,
the fact that perpendicular lines meet at right angles,
terms for triangles such as vertex and side.

Exclusions

Students will not cover

altitudes of shapes other than triangles,
formulas for calculating the lengths of altitudes,
using altitudes to calculate the area of a triangle.
