What are the types of triangles?
An acute scalene triangle is a triangle in which all the angles are less than 90 degrees and all the three side lengths are not equal. A right scalene triangle is a triangle that has an angle that measure 90 degrees and all the three side lengths are not equal.
An obtuse scalene triangle is a triangle in which one of its angle is greater than 90 degrees but less than 180 degrees and all the three side lengths are not equal. A right isosceles triangle is a triangle that has an angle that measure 90 degrees and two sides have an equal length.
An acute equilateral triangle s a triangle in which all the angles are less than 90 degrees and all the three side lengths are of equal lengths. An obtuse isosceles triangle is a triangle in which one of its angle is greater than 90 degrees but less than 180 degrees and two of the side lengths are of equal lengths.
What is the measure of the angle in a triangle?
The sum of angles in a triangle measure 180 degrees. If given two measure of angles, in order to determine the third angle, add the two given angles and subtract from 180 degrees.
