It says, use the proof to answer the question below. So they gave us that angle 2 is congruent to angle 3. So the measure of angle 2 is equal to the measure of angle 3.

The video provides a proof for the sum of an infinite geometric series using limits. When the absolute value of the common ratio (r) is between 0 and 1, the limit of the series converges to a finite sum. The formula for the sum is a / (1 - r), where a is the first term. Created by Sal Khan.

Given figures composed of 2 triangles, complete or find the error in the proof that the triangles are congruent.
In the video, we learn about the sum of an infinite geometric series. The sum converges (has a finite value) when the common ratio (r) is between -1 and 1. The formula for the sum is S = a / (1 - r), where a is the first term.
The area of a rectangle and a parallelogram is found by multiplying the base by the height. For a triangle, the area is half of a parallelogram's, so it's calculated by multiplying the base by the height and then dividing by 2.
