Identify the type of triangle

3/20/2019

 
What type of triangle is shown below?
Picture




​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
