Pythagoras’ Theorem - Finding the Length of Intervals Video Lesson

A video lesson (3 minutes 30 seconds) about using Pythagoras’ Theorem to find the length of intervals.

Level of Difficulty: Beginner (Easy)

Grades: 8thto 11th

Outcomes: Students

• use Pythagoras’ Theorem to find the distance (length) of intervals
• identify the horizontal and vertical lengths of an interval by drawing an imaginary right-angled triangle.

Prior Knowledge:

Students should have already studied the basic of Pythagoras’ Theorem, finding the value of surds and rounding decimals.

Also suitable for Australian Curriculum

• Investigate Pythagoras’ Theorem and its application to solving simple problems involving right angled triangles (ACMMG222)
• Apply Pythagoras’ theorem to solve problems (ACMEM116)

Teaching Idea:

• Teacher explains the Pythagoras’ Theorem using the video lesson (about 3.5 minutes)

Alternative way:

students just watch the video lesson.

The video lesson shows step by step how to use Pythagoras’s Theorem to find the length of intervals.
