Question

13 multiple choice 6 points
determine the type of triangle that is drawn below.
isosceles acute
isosceles obtuse
scalene acute
scalene obtuse

Explanation:

Step1: Check side lengths

Two sides ($QS = 5.93$, $SR = 5.93$) are equal; the third side ($QR=7.59$) is different. By definition, this is an isosceles triangle.

Step2: Check angle measures

All angles are $50^\circ$, $50^\circ$, $80^\circ$. Every angle is less than $90^\circ$, so the triangle is acute.

Answer:

Isosceles Acute
