Answer 1

Answer:

acute angle 30° angle

and 60°and 90°angle is represent right angle

Answer 2

Proof

Argument Reason

1 Angle ∠CPQ has a measure of 30° Constructed using the procedure described in Constructing a 30° angle. See that page for method and proof.

2 Angle ∠CQP has a measure of 60° Constructed using the procedure described in Constructing a 60° angle. See that page for method and proof.

3 Angle ∠PCQ has a measure of 90° Interior angles of a triangle add to 180°. Other two are 30° and 60° See Interior angles of a triangle.

4 PQC is a 30-60-90 triangle (1), (2), (3)
