question 18 of 28
to bisect a right angle, you first construct a(n) — triangle.
a. equilateral
b. scalene
c. obtuse
d. isosceles right

Explanation:

When bisecting a right angle, an isosceles right triangle is constructed first. An isosceles right triangle has two equal sides and a right angle. Bisecting the right angle of this triangle gives two angles of \(45^{\circ}\) each. An equilateral triangle has all angles \(60^{\circ}\), a scalene triangle has all sides and angles of different measures, and an obtuse triangle has one angle greater than \(90^{\circ}\), none of which are directly relevant for bisecting a right angle as effectively as an isosceles right triangle.

Answer:

D. isosceles right
