CBSE Class 9 Triangles Sure Shot Questions
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: (b) We know that, if ΔRST is congruent to ΔUVW i.e., ΔRST = ΔUVW, then sides of ΔRST fall on corresponding equal sides of ΔUVW and angles of ΔRST fall on corresponding equal angles of ΔUVW. Here, given AB = QR, BC = PR and CA = PQ, which shows that AB covers QR, BC covers PR and CA covers PQ i.e.,

Triangles For Class 10 CBSE NCERT
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,
NCERT Exemplar Class 9 Mathematics Chapter 7 Triangles
Solution: In quadrilateral ACBD, we have AC = AD and AB being the bisector of ∠A. Now, In ∆ABC and ∆ABD, AC = AD (Given) ∠ CAB = ∠ DAB ( AB bisects ∠ CAB) and AB = AB (Common) ∴ ∆ ABC ≅ ∆ABD (By SAS congruence axiom) ∴ BC = BD (By CPCT) Ex 7.1 Class 9 Maths Question 2. ABCD is a quadrilateral in which AD = BC and ∠ DAB = ∠ CBA (see figure).
