classification of triangles primary and second parts of triangle

How many parts in the triangle are equal? => 5 or 4 or 0 or 2..

How many parts is the triangle divided into? Are all the parts equal? => 3 equal parts or 4 equal parts or 4 unequal parts or 3 unequal parts..

Introduction - A triangle is a geometrical figure formed by three lines, which intersect each other and which are not all concurrent. A triangle ABC has six parts namely three angles and their sides namely AB, BC, CA. Triangles can be classified either on the..

We have studied that a triangle has six parts or six elements viz three sides and three angles. From geometry, we know that when any three elements are given of which necessarily a side is given, the triangle is completely determined i.e, remaining three elements can b..

A triangle is a geometrical figure formed by three lines, which intersect each other and which are not all concurrent. A triangle ABC has six parts namely three angles and their sides namely AB, BC, CA. Triangles can be classified either on the basis of the s..

If a ray rotates about the starting initial position, in anticlockwise direction, comes back to its original position after 1 complete revolution then it has rotated through 360 o . 1 complete rotation is divided into 360 equal parts. Each part is 1 o . Each part (1 o ..

(corresponding angles of congruent triangles) Compare D GBH and D DHF, GH = FH (data) BF+FH = GD+GH (BF=GD and FH=GH) i.e., BH = DH (proved above) BG = DF (congruent parts of congruent triangles..

Summary - Midpoint Theorem The straight line joining the mid-points of two sides of a triangle is parallel to and equal to half the third side. Converse of mid point theorem - The straight line drawn through the mid point of one side of a triangle, parallel to another, bisects t..

In triangles ABC and ADC, AB=CD (given) AC = AC (common side) (corresponding parts of corresponding triangles) Since these are alternate angles, AD||BC. Thus in the quadrilateral ABCD, AB||CD and AD||BC. ABCD is a parallelogr..

Question: ABC is a triangle and DE is a line segment meeting AB in D and AC in E such that DE||BC and divides D ABC into two parts of equal area. Find [3 Mark] Answer: Given: Area ( D ADE) = Area (trapezium DECB) ... (1) Area ( D ABC) = Area ( D ADE) + A..
