Question

use your protractor, compass and writing utensil to construct the follo triangles according to the classifications given: 1.) obtuse isosceles triangle. (angle = 120° and legs 2 inches long.)

Explanation:

Step1: Draw base segment

Mark point A, use compass to draw 2-inch segment AB.

Step2: Construct 120° angle at A

Place protractor at A, mark 120° from AB, draw ray AC (2 inches).

Step3: Connect vertices

Join points B and C to form triangle ABC.

Answer:

The constructed obtuse isosceles triangle has vertices A, B, C with AB=AC=2 inches and ∠BAC=120°.
