Why are there no NCERT solutions of try these ? Because, in chapter congruence of triangles there is mainly try these and only 2 exercises .

--= ++= -+= +-=

Give three examples of shapes with no line of symmetry.

What letters of the English alphabet have reflectional symmetry (i.e., symmetry related to mirror reflection) about.

(a) a vertical mirror

(b) a horizontal mirror

(c) both horizontal and vertical mirrors

answer the try these which is given on pg 140 of maths ncert book of class 7th

try these page 129-130 (vi)plz class 7

write the: side opposite to the vertex Q of trianglePQR

angle opposite to the side LM of triangleLMN

vertex opposite to the side RT of triangleRST
