The area, T, of the triangle and the area , R, of the rectangle, both in sq cm, satisfy the relationship R = T². If the sides of the rectangle are in the ratio 1 : 3, then the length, in cm, of the longer side of the rectangle, is 18 21 24 27 2 / 10 From the interior point of an equilateral triangle, perpendiculars are drawn on all three sides. The sum of the lengths of the perpendiculars is 's'. Then the area of the triangle is S²/(2√3) 2S²/(2√3) S²/√3 √3 S²/2 OPTION 1 OPTION 2 OPTION 3 OPTION 4 3 / 10 In a triangle ABC , ∠ BCA =50°. D and E are points on AB and AC, respectively, such that AD = DE. If F is a point on BC such that BD = DF, then ∠ FDE, in degrees, is equal to 80 100 96 72 4 / 10 A circle of diameter 8 inches is inscribed in a triangle ABC where ∠ABC = 90°. If BC = 10 inches then the area of the triangle in square inches is Check 5 / 10 In a triangle ABC, AB = AC = 8 cm. A circle is drawn with BC as diameter passes through A. Another circle drawn with center at A passes through B and C. Then the area, in sq.cm. of the overlapping region between the two circles is 16(𝝅 - 1) 32( 𝝅 - 1) 32𝝅 16𝝅 6 / 10 Suppose the medians BD and CE of a triangle ABC intersect at a point O. If the area of triangle ABC is 108 sq. cm. , then the area of triangle EOD in sq. cm., is Check 7 / 10 In triangle ABC , altitudes AD and BE are drawn to the corresponding bases . If angle BAC = 45˚ and angle ABC = θ , then AD / BE equals √2 sin 𝜽 √2 cos 𝜽 (sin 𝜽 + cos 𝜽) / √2 1 8 / 10 Let ∆ ABC be an isosceles triangle such that AB and AC are of equal length. AD is the altitude from A on BC and BE is the altitude from B on AC. If AD and BE intersect at 'O' such that angle AOB = 105 ˚, then AD/ BE equals 2 sin 15° cos 15° 2 cos 15° sin 15° 9 / 10 A triangle is drawn with its vertices on the circle C such that one of its sides is a diameter of C and the other two sides have their lengths in the ratio a : b .
