Classify the triangle by its angles and its sides explain how you knew which classifications to use.

This triangle is an acute triangle because all three angles measure less than 90 degrees. It is also an isosceles triangle because two of its sides are equal in length. We can tell this because the triangle has two sides labeled as "5 cm" and one side labeled as "4 cm".

Did you know that triangles can be classified based on their angles and sides? When classifying a triangle by its angles, it can be categorized as either acute, right, or obtuse. Acute triangles have all angles less than 90 degrees, right triangles have one angle equal to 90 degrees, and obtuse triangles have one angle greater than 90 degrees. Similarly, triangles can also be classified by their sides. A triangle with all sides of equal length is called an equilateral triangle. A triangle with two sides of equal length is known as an isosceles triangle, while a triangle with no sides equal in length is called a scalene triangle. To determine the classification of a triangle, you can examine the measures of its angles using a protractor or ruler, and measure the lengths of its sides using a ruler. By comparing these measurements to the definitions of the different classifications, you can determine the appropriate categorization of the triangle.
