Question

. Classify the triangle according to side length and angle measurement.

Answer 1

An Isosceles right triangle has one right angle and two 45 degree angles. Isoceles meaning two sides are the same so two angles are the same. Right meaning one angle is 90 degrees.  
There is no such thing as a Right Equilateral triangle. In an Equilateral triangle, all sides are the same length and all angles are 60 degrees. 
 An obtuse scalene triangle has all angles and sides of different measure and length but one angle is obtuse(over 90 degrees) 
 An acute scalene triangle has all angles and sides of different measure and length and all angles are less than 90 degrees. 
 A right triangle has one angle that is exactly 90 degrees and the side opposite to that angle is called the hypotenuse. The hypotenuse has the longest measurement of the triangle.
