#EQUILATERAL ISOSCELES TRIANGLE WORKSHEET HOW TO#

These worksheets explain how to identify these types of triangles. The radius of an equilateral is half the radius of a circumcircle. You may construct an equilateral triangle of a provided side length using a straightedge and a compass. It is a specific case of a regular polygon, but here, with three sides. The Equilateral has a property with all three interior angles. The examples of the isosceles are the golden triangle, isosceles right triangles, and the faces of bipyramids as well as certain Catalan solids.Įquilateral - This is a triangle that has all three sides equal or of the same length. You can find the other two isosceles triangles if you have one interior angle.

These isosceles shapes are used in regular polygon areas plus, the triangles are called 45-45-90. The congruent sides are called legs from the vertex angle, and the other two are base angles. Isosceles - Suppose two sides of a triangle are congruent, the angles that are opposite are congruent. What Are Equilateral and Isosceles Triangles? When it comes to angles of triangles: acute (all angles are acute), right (one right angle), obtuse (one obtuse angle), and equiangulars (you guessed it have all equal angles). If all sides are equal it is called equilateral. The Isosceles Triangle Theorem tells us that if you have an isosceles triangle the angles opposite the congruent sides are also congruent. If two sides of a triangle are congruent that are considered the same in all respects. If the length of two sides of the triangle are equal it is called isosceles. If all the lengths of their sides are different it is scalene. This worksheet is a great resource for the 5th, 6th Grade, 7th Grade, and 8th Grade.Triangles are often classified by either their number of sides or the measures of their angles. This Triangle Worksheet will produce problems where you find the centroid from a the vertices of a triangle. This worksheet is a great resource for the 5th, 6th Grade, 7th Grade, and 8th Grade.įind the Centroid from Vertices Worksheets This Triangle Worksheet will produce problems to calculate the centroid from a graph. This worksheet is a great resource for the 5th, 6th Grade, 7th Grade, and 8th Grade.įind the Centroid from a Graph Worksheets You may select the problem types to be integers, decimals, or algebraic expression. This Triangle Worksheet will produce median problems. This worksheet is a great resource for the 5th, 6th Grade, 7th Grade, and 8th Grade. This Triangle Worksheet will produce angle bisector problems. You can choose a single variable or an algebraic expression for the unknown angle. This Triangle Worksheet will produce exterior angle theorem problems. You can choose between interior and exterior angles, as well as an algebraic expression for the unknown angle. This Triangle Worksheet will produce triangle angle sum problems. This Triangle Worksheet will produce triangle side inequality problems. Triangle Inequalities of Sides Worksheets This Triangle Worksheet will produce triangle angle inequality problems. Triangle Inequalities of Angles Worksheets Since the total degrees in any triangle is 180, an obtuse triangle can only have one angle that measures more than 90. In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle. You can choose between whole numbers or decimal numbers for this worksheet. The Obtuse Triangle has an obtuse angle (an obtuse angle has more than 90). This Triangle Worksheet will produce triangle inequality theorem problems.

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 worksheet is a great resources for the 5th, 6th Grade, 7th Grade, and 8th Grade. If all three sides of a triangle are congruent (the same length), it is called an equilateral triangle.

This Triangle Worksheet will produce nine problems for solving the area and perimeter of different types of triangles. This worksheet is a great resources for the 5th, 6th Grade, 7th Grade, and 8th Grade.Īrea and Perimeter of Triangles Worksheets You may select equilateral, right scalene, right isosceles, obtuse scalene, obtuse isosceles, acute scalene and acute isosceles. This Triangle Worksheet will produce twelve problems for identifying different types of triangles. This worksheet is a great resources for the 5th, 6th Grade, 7th Grade, and 8th Grade. This Triangle Worksheet will produce a useful definitions, facts and formulas handout for the students. Detailed Description for All Triangle Worksheets
