  • See diagram. You can see a general quadrilateral with AB || DC and AD = BC. Extend the sides AD and BC till E and F as shown. As AB and CD are two parallel lines and AD intersects them both, the angles D and EAB are same. But angle EAB = 180 - A. so, angle D = 180 - A

  • Types of Quadrilateral. Quadrilaterals are polygons which have four sides and four angles. Quadrilaterals may be irregular or regular. A polygon is regular if all its sides are of equal length and all its angles are of equal size. Figure 20 and Figure 21 both show a number of different types of quadrilateral.

PR be a secant such that it intersects the circle at … Geometry – SSC CGL Tier 1 previous year questions Read More » Let the measure of the smaller angle be 5x and the measure of the larger angle be 13x. Since the sum of the measures of the two acute angles of a right triangle is 90% (KEY FACT J3): 5x + 13x = 90 18x = 90 x = 5. Therefore, the measure of the larger angle is 13 × 5 = 65°. Ratios can be extended to three or four or more terms.
EXERCISE 8.1 . Question 1. The angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. Find all the angles of the quadrilateral. Question 2. If the diagonals of a parallelogram are equal, then show that it is a rectangle. A Cyclic Quadrilateral. DRAWING 3 - Figure 18. If two triangles are drawn within a circle with a common diameter of the circle as a base and with the vertical angles touching the circumference of the circle, they are said to form a cyclic quadrilateral. Quadrilaterals - plane figures with four sides - are described later in this chapter.
