If none of the sides are equal length it is called a scalene triangle.
If a triangle has two equal sides (in length) it referred to as isosceles. In an equilateral it has all equal side lengths. We can also classify them by their sides. Classifying triangles (equilateral / isosceles / scalene / right) Grade 5 Geometry Worksheet 1. Problem 1 : Use the diagram ofABC shown below to prove the Base Angles Theorem. We can classify them by the angles that exist with a triangle. ISOSCELES EQUILATERAL AND SCALENE TRIANGLE WORKSHEET. We explore the six main classifications of triangles. Obtuse -Obtuse are those that have an angle that measures more than 90 degrees but less than 180 degrees.Īcute -Acute are those that have all the angles of less than 90 degrees.Įquiangular -Equiangulars are those that have all its angles of the same measurement. Right -Right are those that have at least one angle of 90 degrees. Scalene -Scalenes are those that have all three sides of different measurements.īased on their angles, triangles are classified as the following four types: Isosceles - Isosceles are those shapes that two sides of equal measurement Classifying triangles (equilateral / isosceles / scalene / right) Grade 4 Geometry Worksheet 1. We need two congruent angles.īased on their sides, triangles are classified as the following three types:Įquilateral - As the name implies, equilateral are those that have all the three sides of the same measurement. Obtuse versions have angles that are greater than 90 degrees and two acute angles. We need one right angle and two acute angles to make right angles. All three angles of an acute triangle are less than 90 degrees. All equilateral triangles are isosceles triangle that has two congruent sides of the triangle.Īngles - We can classify triangles by their angles and it has different types. All three sides of equilateral triangle have the same measurement. In an isosceles triangle, two sides have exactly the same measurement. Three sides of the scalene triangle have different measurements. You will need to mark triangle sides that are congruent.
Sides - An accurate measurement of triangle sides helps us to classify triangles. We differentiate them by their sides or angles. Substitute the decimal dimensions in the formula A 1/2 b h to compute the area of the isosceles triangles. Find the height of the isosceles triangles presented in these worksheets for grade 6, grade 7, and grade 8. These shapes has different type of shapes and sizes. Area of Scalene Triangles Decimals- Type 1. The measurements of these angles and sides may be different or the same size, there only maybe one distinctive angle any two angles or sides may be of equal measurements. They are classified based on their angles and sides. Triangles are regular polygons with three sides and three angles.
