A Triangle Has An Angle That Measures 90\Xb0. What Type Of Triangle Could It Be? (Choose All That Apply), A. Scalene, B. Acute, C. Isosceles, D. Right

A triangle has an angle that measures 90°. What type of triangle could it be? (Choose all that apply)

a. scalene
b. acute
c. isosceles
d. right

 

Answer:

A triangle with an angle that measures 90° can be (a)scalene,  (c)isosceles, and (d)right.

Step-by-step explanation:

a) Scalene - YES

If the triangle has a 30°-60°-90° angle measurements, then it has no equal sides, too. Therefore, it is scalene.

b) Acute - NO

A triangle with an angle measuring 90° is not acute triangle. An acute triangle has all angles measuring less than 90°.

c.)  Isosceles - YES

An triangle with a 90-degree angle can be have angle measurements of 45°-45°-90°. Therefore, if two angles are congruent, the sides opposite to these angles are congruent, too. An isosceles triangle has exactly two equal sides.

d.) Right - YES

A right triangle has a 90-degree angle.
