Jessica calculated the missing side length of one of these triangles using the Pythagorean Theorem. Which triangle was it? E
F
G
H

G

Step-by-step explanation:

We can find a missing length of a triangle using a Pythagorean theorem if and only the triangle is a right angled triangle.

The side of the missing length is:

a^+b^=c^

2^+4^=c^

4+16=c^

20=c^

Step-by-step explanation:

values of coefficients are:

vertex form is , where and

Inserting to the vertex form, we get:
