Download Classifying Triangles Worksheet PDFs Remember that for each triangle, the three interior angles must add up to 180 degrees. It creates the basic foundational concept of triangles that can be used in sister topics such as Geometry. Instructions: For each triangle, find the unknown angle (X). 3 Tina wants to sew a piece of fabric into a scarf in the shape of an isosceles triangle, as shown in the accompanying diagram. The vertex angle formed at the peak of the roof is 84°. 2 The accompanying diagram shows the roof of a house that is in the shape of an isosceles triangle. The problems are partly from Art of Problem Solving, by Richard Rusczyk. 1 In the diagram of ABC measure of B is 40°. We use these properties to find missing angles in composite figures. Equilateral triangles have all side lengths equal and all angle measures equal. Benefits of Classifying Triangles Worksheetsīy solving several problems available in the classifying triangles worksheets, a student gets a better idea of which properties need to be applied to what triangle. Isosceles triangles have two congruent sides and two congruent base angles. As a student progresses through the worksheets, he gets a clear idea of how to categorize the triangles. Based on sides they can be classified into a right triangle, acute-angled triangle and obtuse-angled triangle. Based on their sides triangles can be classified into an equilateral triangle (all equal sides), isosceles triangle (two sides equal) and scalene triangle (unequal sides). Classifying triangles worksheets enable students in identifying the type of triangles based on their sides or angles or both.
