Medians and Centroid of a triangle

Home Geometry Medians and Centroid of a triangle Medians and Centroid of a triangle Worksheets A Median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle. The medians of a triangle are concurrent and they intersect in one common point. The Centroid of a triangle is the point of intersection of all the three medians of a triangle. The centroid always divides each median into two parts, in the ratio 2:1. Medians and Centroid of a triangle worksheets free download pdf

Pythagorean Theorem

Home Geometry Pythagorean Theorem Pythagorean Theorem Worksheets What is Pythagorean Theorem? Pythagorean Theorem or Pythagoras Theorem states, “In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides”. This can be expressed as c2 = a2 + b2; where ‘c’ is the hypotenuse and ‘a’ and ‘b’ are the two legs of the triangle. The Pythagorean theorem can be used to: To check if a triangle is right-angled To determine the speed of sound in the ocean by oceanographers To find the range and sound source by aerospace scientists and meteor.

Perimeter of Triangles

Home Geometry Perimeter of Triangles Perimeter of Triangles Worksheets What is Perimeter?Perimeter of a Polygon is the total length of its boundaries. How to calculate the perimeter of a triangle?To calculate the perimeter of a triangle you need to add the length of the sides. Also, in these worksheets, with the given perimeter you would understand that you find the length of a missing side. Imagine walking around a triangular park. The Perimeter is the total distance you walked around the park once. With these worksheets, you would practically understand  why we would need to calculate the perimeter of triangles in real life. The fornula to calculate the perimeter is given in each sheet. Follow the example to solve the problemss in these free downloadable perimeter worksheets. From Grade 5 through Grade 7.

Types of Triangles

Home Geometry Types of Triangles Types of Triangles Worksheets A triangle is a three- sided polygon having three angles. Thus, there are six basic types of triangles, three are classified according to their sides and the other three are classified according to their angles. Let us discuss the different types of triangles and their properties in detail. Classification by sides (length of their sides) In an equilateral triangle, all the sides are congruent. That is, all three sides of the triangle are equal. Since all the sides are equal, all the interior angles will also be equal. To find the measure of each angle, an important property of a triangle is to be recalled. ‘The sum of the angles of a triangle is 180 degrees’. Thus dividing 180 to three equal parts, it’s 60. Each angle of an equilateral triangle is 60 degrees. Therefore, an equilateral triangle is also known as an equiangular triangle. In an isosceles triangle, only two sides are equal. If two sides are equal, then their angles will also be equal. Thus, the angles opposite to the equal sides are equal. In an acute triangle, all three interior angles are acute. An acute angle is an angle less than 90 degrees. It also means that all three angles of an acute triangle are less than 90 degrees. In an obtuse triangle, one angle of the triangle is always greater than 90 degrees, which is called obtuse. Thus a triangle in which one of the angles measures more than 90 is an obtuse triangle. In a right triangle, one angle is always equal to 90 degrees. The representation of this triangle is shown below. The side opposite to the right angle will be the longest side and is called the hypotenuse.  Types of Triangles worksheets free download pdf

Area of Triangles

Home Geometry Area of Triangles Area of Triangles Worksheets Have you seen bridges that are triangle in shape? In fact bridges are made up of multiple triangles. Forget bridges, your pizza slices are triangular in shape and definitely you would not have missed to recognize it. Thus, triangles are incredibly common and are used in our everyday life.Lets learn to calculate the area of a triangle. Here, the area is the region occupied by the triangle. As already discussed before in types of triangles, we would find the area of equilateral triangles, isosceles triangles, and scalene triangles.Area of Triangles worksheets teaches the different types of triangles, computation of  the area and perimeter, unde concepts of median & centroid, and pythagorean theorem.
