Answer:
Each piece has three sides and thus three angles.
With measure of one angle is 90° and other two are 45°
Step-by-step explanation:
Given : Jeff has a square piece of art paper he cuts across it from one corner to the opposite corner to make two pieces,
We have to explain the total number of sides and angles in both of the New shapes.
Since, A square has 4 sides and 4 angles with measure of each angle is 90°.
When we cut it from one corner to the opposite corner to make two pieces, we get two triangles.
Since, Each piece has three sides and thus three angles.
With measure of one angle is 90° and other two are 45°
As shown in figure below,
