How many different triangles can be drawn with AB = 5 cm, ∠A = 40° and ∠B = 60°?

Class 9SAS, ASA and AAS CongruenceGeometry — Triangles
  • AInfinitely many
  • BTwo
  • CExactly one
  • DNone

Step-by-Step Solution

Two angles with the side between them fix the triangle completely — that is why ASA is a congruence rule. Any two such triangles are congruent.
Answer: C) Exactly one

AB and CD bisect each other at O, as shown. By which rule is △AOC ≅ △BOD?Since △AOC ≅ △BOD when AB and CD bisect each other at O, what can be said about AC and BD?In △ABC, AB = AC and AD bisects ∠A, meeting BC at D. By which rule is △ABD ≅ △ACD?In isosceles △ABC (AB = AC), the bisector of ∠A meets BC at D. What is ∠ADB?In a kite ABCD, AB = AD and diagonal AC bisects ∠BAD. If ∠ABC = 100°, what is ∠ADC?
