(You only have to make but one copy of the di. One page is the triangle sort and the other page is the directions for the activity. Many of these problems take more than one or two steps, so look at it as a puzzle and put your pieces together!īelow you can download some free math worksheets and practice. This activity lets students practice classifying triangles by angles, (acute, right, obtuse), and by sides, (equilateral, isosceles, and scalene). If you don’t remember that last step, don’t worry! You can just take two more steps and find the 3 rd angle of the bottom triangle and subtract it from 180°to find the exterior angle. We need a few pieces of the puzzle before we can find the measure of x. They ultimately want to find the measure of that exterior angle. There’s actually at least three different ways that you can answer this problem. Find a piece at a time and put them together until you reach your answer! You have to look at these problems as “puzzles” because sometimes you need to find a part that they are not asking for in order to find the final result. Let’s see if we can put these properties to work and answer a few questions.

So, in EVERY equilateral triangle, the angles are always 60°. If just two of a triangle’s sides are congruent, then it is called an isosceles triangle. Equi - refers to things that are the same or equal, and lateral means sided. This is because all angles in a triangle always add up to 180°and if you divide this amongst three angles, they have to each equal 60°. If all three sides of a triangle are congruent (the same length), it is called an equilateral triangle.

The angles, however, HAVE to all equal 60°. The sides can measure anything as long as they are all the same. When all angles are congruent, it is called equiangular. In an equilateral triangle, all sides are congruent AND all angles are congruent. Here are some diagrams that usually help with understanding. Since two sides are congruent, it also means that the two angles opposite those sides are congruent. Well, some of these types of triangles have special properties!Īn isosceles triangle has two sides that are congruent. Since the sum of the interior angles is 180 degrees, every angle. An isosceles triangle is a triangle with (at least) two equal sides. A scalene triangle is a triangle that has three unequal sides. Note : An equilateral triangle is a triangle in which all three sides are equal. Write a Python program to check if a triangle is equilateral, isosceles or scalene. Properties of an equilateral triangle are: It has 3 equal sides. Python Conditional: Exercise - 36 with Solution. It is a special case of the isosceles triangle where the third side is also equal. We’ve learned that you can classify triangles in different ways. An equilateral triangle is the one in which all the three sides are equal.
