Question

You want to divide a square piece of paper into two equivalent triangle if the square measures 20m in each side what will the third side measure

Answer 1

20 √2

It would be a 45 45 90 triangle. So both sides are X (20) and the missing side is X √2 (20 √2).

Answer 2

Answer: 20 √2 cm or 28.3 cm

Step-by-step explanation:

Folding a paper diagonally will result in two triangles. You know each side of the square piece of paper is 20 cm, so a^2 and b^2 is 20 cm.

Use the formula ‘a^2 + b^2 = c^2’

20^2 + 20^2 = c^2

400 + 400 = 800

√800 = 20 √2 or 28.3 cm
