Moreover, both pairs of opposite angles are also congruent and the consecutive angles are supplementary. Question 6: What are the 5 properties of a parallelogram?Īnswer: The five properties of a parallelogram are that both pairs of opposite sides are parallel and congruent. Each diagonal divides the quadrilateral into two congruent triangles. One pair of opposite sides is parallel and equal in length. Question 5: What are the diagonals of a parallelogram?Īnswer: The diagonals bisect each other. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c. Question 4: How do we find the perimeter of a triangle?Īnswer: To calculate the perimeter of a triangle, add the length of its sides. Further, the perimeter of a parallelogram is the sum of the lengths of its four sides. Over here, b is the length of one base and h refers to the height. Question 3: What is the area and perimeter of a parallelogram?Īnswer: The area A of a parallelogram is given by the formula. Question 2: The hypotenuse of a right-angled isosceles triangle is 5 cm The area of the triangle is:Īnswer : B. Therefore, the area of the given parallelogram = 10 × 3.5 = 35 cm² The area of parallelogram is given by, base × height cm². The area of the parallelogram is:Īnswer : B. Question 1. The base and the corresponding altitude of a parallelogram are 10 cm and 3.5 cm respectively. To find the area of a triangle you need 2 things: the base and the height. The height of the triangle is the perpendicular drawn on the base of the triangle. Area of the triangle is calculated by the formulaĪrea of a Triangle = 1/ 2 × base × height Solved Examples For You The isosceles triangle means, at least two of the triangle side lengths are similar.Equilateral means that every side length in a triangle is similar.Scalene, meaning that every side length in a triangle is different.Therefore, you can count on two different ways to classify the types of triangle: Obtuse Triangle: Triangle in which one of the angles stays obtuse is called as an obtuse triangle.įurther, triangles can be classified depending on the number of congruent sides that means the side length.Right Angled Triangle: It is a form of a triangle wherein one particular angle is a right angle.Acute Triangle: This is a triangle in which each of the angles is acute and measure is less than 90°.Classification triangles based on angles are namely: The basic elements of the triangle are sides, angles and vertices. In geometry, any three points, specifically non-collinear, form a unique triangle and separately, a unique plane (known as two-dimensional Euclidean space). Triangles are basic shapes that we come across in our day to day life.Ī triangle is a simple closed curve or polygon which is created by three line-segments. The pizza when you cut it into equal four pieces you get each part in triangular shape. When you think of drawing a hut, you draw a triangle having three sides. The diagonals of a parallelogram bisect each other.If one angle is right, then all angles are right.Perimeter of Parallelogram = 2(a+b) Properties of Parallelogram The area of and perimeter of parallelogram is given by (where b = base length, a = adjacent side length and h = height from the base to the opposite side): Browse more Topics under Perimeter And Area The sum of the angles of a parallelogram is 360°. In a parallelogram, the angles are not right angles. So, when the diagonals of a parallelogram bisect each other, it divides it into two congruent triangles. Suppose if every pair of opposite sides of a quadrilateral is equal, then it becomes a parallelogram.ĭiagonals of a parallelogram bisect each other. Because of the parallel lines, opposite sides are equal and parallel. What does ‘parallel lines’ mean? Parallel lines are the two lines that never meet. A parallelogram is a slanted rectangle with the length of the opposite sides being equal just like a rectangle.
