What type of triangle is shown below?
A.) Equiangular B.) Right Isosceles C.) Acute Scalene D.) Obtuse Scalene
Identify the measure of the third angle of the triangle.
Angles of a triangle add up to 180°. 180  (110 + 28) {subtracted given angles from 180° to determine missing angle} = 180  138 {worked inside parentheses} = 42 {subtracted} Angles of triangle are 28°, 42°, and 110° If no angles are congruent, then none of the sides are congruent. If no sides are congruent, it is scalene. If an angle is larger than 90°, it is an obtuse triangle. D.) Obtuse Scalene Ask Algebra House Comments are closed.
