Question

classify the four angles of the quadrilateral. question 13

Explanation:

Step1: Recall angle - type definitions

An acute angle is less than 90°, a right - angle is equal to 90°, and an obtuse angle is greater than 90° and less than 180°.

Step2: Classify ∠A

∠A = 94°, since 90° < 94° < 180°, ∠A is an obtuse angle.

Step3: Classify ∠B

∠B = 106°, since 90° < 106° < 180°, ∠B is an obtuse angle.

Step4: Classify ∠C

∠C = 70°, since 0° < 70° < 90°, ∠C is an acute angle.

Step5: Classify ∠D

∠D = 90°, so ∠D is a right - angle.

Answer:

∠A: Obtuse
∠B: Obtuse
∠C: Acute
∠D: Right
