In Fig. 8.40, prove that `Delta s` OAM and OBN are congruent and hence prove that `AM= BN.`

Prove that DeltaSQRandDeltaTPR are congruent and SR = TR.

In the fig. prove that p||m

In Figure,AC=BC,/_DCA=/_ECB and /_DBC=EAC Prove that triangle DBC and EAC are congruent and hence DC=EC and BD=AE

In the given fig. KN, PA and PB are tangents to the circle. Prove that : KN = AK + BN .

Prove that in a kite ABCD Delta ABC and Delta ADC are congruent.

Prove that in a kite ABCD, /_\ABC and /_\ADC are congruent.

Prove that in a kite ABCD, DeltaABC and DeltaADC are congruent.

BC is an equilateral triangle. A circle is drawn with centre A so that it cuts AB and AC at points M and N respectively. Prove that BN = CM

In triangle ABC, the sides AB and AC are equal. If P is a point on AB and Q is a point on AC such that AP = AQ, prove that : (i) triangle APC and AQB are congruent. (ii) triangle BPC and CQB are congruent.
