Congruent Triangles Examples Grade 9. Give a reason to support your answer. Two triangles are said to be congruent if their sides have the same length and angles have same measure.
Multiplication property of equality 10 write the given related to corresponding angles. 9 10 8 here, by comparing we will get thatside(i.e. 10) opposite to longer angle (90°) is longer.
The triangles are also right triangles and isosceles.
(ii) sides ne and rp are congruent (given).(iii) sides em and pq are congruent (given). Two geometrical figures are said to be congruent if they are identical in every respects. From the above three points, we get ass. Congruence of triangles class 9 helps the students to understand the concept of congruence in a different perspective. But, ass does not work for congruent triangles. Sss, sas and asa' and thousands of other practice lessons.
