Proving theorems on isosceles triangle
WebbTRIANGLES -Part 1 Classifica on of Triangles A triangle has 3 sides, 3 ver ces, 3 angles They have been classified as follows: Based on sides Based on angles 1) Scalene triangle 2) Isosceles triangle 3) Equilateral triangle 1) Acute triangle 2) Right triangle 3) Obtuse triangle Inequali es of Triangle 1) If PQ > PR then PRQ > PQR i.e. R > Q WebbThere are two characteristics of isosceles triangles. The first is that the two sides are equal. The second is that each base angle is equal. On the other hand, right triangles have a congruence theorem. There is a congruence theorem available only for right triangles, so try to remember it.

WebbProblematic Start. The problem. Let AC and BD intersect at E, then E is the midpoint of BD. You can’t say E is the midpoint without giving a reason. Let M be the midpoint of BD, then let k be the line containing AMB, then by the theory of isosceles triangles, this line bisects angle BAC..
