What is CPCT rule of congruence of triangles?

what is the full form of SSS, SAS, ASA and fast

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 any two real-life examples for congruent shapes.

In a squared sheet, draw two triangles of equal areas such that

(i) The triangles are congruent.

(ii) The triangles are not congruent.

What can you say about their perimeters?

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

I still din't understand diffrence between SAS and RHS criterion in the above Video.

what is the difference between ASA and AAS congreunce critaria? and AAS is not mentioned in study material but given in chapter test. Q6

ABC & DBC are both isosceles trangle on a common base BC such that a & D lie on the same side of BC. Are trangle ADC & ADB congruent? Which condition do you use? If angle BAC=40 & angle BDC = 100 degree, then find angle ADB?

what is pythagoras property

In triangle ABC, angle B = angle C show that triangle ABC is congruent to triangle ACB [ by ASA congruence rule].

ARE THE SIMILARITY CONDITIONS OF TWO TRIANGLES SAME AS THE CONGRUENCY ONES?

is there is any AAA congruence criterion?

Q4) State the correspondence between the vertices, sides and angles of the following pairs of congruent triangles.

(i)$\u2206$ABC $\cong $ $\u2206$XYZ (ii) $\u2206$ABC $\cong $ $\u2206$YZX

(iii) $\u2206$PQR $\cong $ $\u2206$EFG (iv) $\u2206$PRQ $\cong $$\u2206$EFG

Q5) Prove that the bisector of the top angle of an isosceles triangle bisects the base at right angles.

Q6) Show that in an isosceles triangle, the angles opposite equal sides are equal.(Hint. Draw a perpendicular to the unequal side from the vertex.)

Q7) In the isosceles $\u2206$ABC , AB = AC. Perpendiculars BD and CE are drawn from the vertices B and C, to the opposite sides. Show that BD = CE.

Q8) In the square ABCD, show that the two triangles ABC and ADC are congruent to each other.
