Question

12. A square piece of paper measuring 8 inches on each side is folded in half forming a triangle. It is then folded in half again to form another triangle.
Find the angles of the resulting triangle.

Help please and thanks! I always give brainliest!

Answer 1

Answer:

Angles in resulting triangles are 90, 45, and 45

Step-by-step explanation:

A square starts out with four angles of 90 degrees. When you fold a square in half forming a triangle, you keep one of the 90 degrees (vertice #1), and the other 2 vertices will be 2 90 degree angles folded in half (90/2 = 45) (vertices 2 and 3). Then, by folding again forming another triangle, you keep one of the 45 degree angles (vertice 1), and fold the other 90 degree angle in half, making another 45 degree angle (vertice 2). Since a triangle is 180 degrees and 45+45=90, 180-90=90, meaning the resulting vertice will be 90 degrees.

Answer 2

Answer: 90,45,45

Step-by-step explanation:

The triangle is a right triangle meaning a 90 degree angle and 2 acute 45 degree angles.

90+45+45=180

A triangle has 180 degrees in total.
