Geometric figures are sets of points and lines that form shapes. Knowing how to identify triangles is important to understanding the basic properties of triangles. Introduce your child to the concept of triangles with these great introductory worksheets for grade 4 to 7.
Does your child know how to classify triangles? In this article, you will know about the properties of triangles. Geometry worksheet will help to recognize angles and sides of triangles.
Properties of triangle
A triangle is a simple closed curve made of three line segments. Triangle has three vertices,three sides and three angles.
How to classify triangles
We can classify triangles according to their Sides and angles.
Types of triangles based on their sides
: If the triangle has three equal sides, and therefore three equal angles, then the triangle is called Equilateral triangle.
: If the triangle has two equal sides, and one unequal, it is isosceles triangle.
: If a triangle has sides of three different lengths, and therefore three different angles, we call it a scalene triangle.
Types of triangles based on their angles
: A triangle having all acute angles (less than 90°) in its interior is Acute-angled triangle.
: A triangle that has a right angle in its interior is Right-angled triangle.
: A triangle having an obtuse angle
(greater than 90° but less than 180°) in its interior Obtuse-angled triangle.
What is the median of a triangle
A median of a triangle is a line from a vertex of the triangle to the midpoint of the side opposite that vertex. Every triangle have 3 medians. These three medians meet at one point - centered of the triangle.
What is the altitude of a triangle
In a triangle, a segment drawn through a vertex Perpendicular to the opposite side is called the altitude or hight of the triangle. The three altitudes of any triangle are concurrent.
Activities for triangle concept:
Activities help students become familiar with the basic principals and concepts of Geometry.
1. Triangle with strings:
First students have to cut two pieces of string in identical lengths. They then use a protractor to connect the strings to the paper to create a triangle. Once the triangle is constructed, students have to measure each side of the triangle and define its properties.
Make a several cut out of triangles with cardboard in different sizes. Then measure each triangle by their sides and their angles.
Try to classify triangles as you can.
