NCERT Exemplar Class 9 Mathematics Chapter 7 Triangles
Question 1. Find the measure of each exterior angle of an equilateral triangle. Solution: We know that each interior angle of an equilateral triangle is 60°. ∴ Each exterior angle = 180° - 60° = 120° Question 2. If in ∆ABC, ∠A = ∠B + ∠C, then write the shape of the given triangle. Solution: Here, ∠A = ∠B + ∠C

Solution: As per given in the question, ∠DAB = ∠CBA and AD = BC. (i) ΔABD and ΔBAC are similar by SAS congruency as AB = BA (common arm) ∠DAB = ∠CBA and AD = BC (given) So, triangles ABD and BAC are similar i.e. ΔABD ≅ ΔBAC. (Hence proved). (ii) As it is already proved, ΔABD ≅ ΔBAC So, BD = AC (by CPCT) (iii) Since ΔABD ≅ ΔBAC So, the angles,

Answer: c Explanation: Given, AB = BC Hence, ∠A=∠C And ∠B = 70 ° By angle sum property of triangle we know: ∠A+∠B+∠C = 180 ° 2∠A+∠B=180 ° 2∠A = 180-∠B = 180-70 = 110 ° ∠A = 55 ° 2) For two triangles, if two angles and the included side of one triangle are equal to two angles and the included side of another triangle. Then the congruency rule is: a.
