Find out the value of x .

To proof

SAS congurence property

In this property two sides and one angle of the two triangles are equal.

in the Δ ADC and ΔBDC

(1) CD = CD (common side of both the triangle)

(2) ∠CDA = ∠ CDB = 90 °

( ∠CDA +∠ CDB = 180 ° (Linear pair)

as given in the diagram

∠CDA  = 90°

∠ CDB = 180 ° - 90°

∠ CDB = 90°)

(3) AD = DB (as shown in the diagram)

by using the SAS congurence property .

AC = BC

(Corresponding sides of the congurent triangle)

As given

the length of AC is 2x and the length of BC is 3x - 5 .

2x = 3x - 5

3x -2x =5

x = 5

The value of x is 5 .

Hence proved

We will prove the SAS congruence property

(In this property two sides and one angle of the two triangles are equal the, the two triangles are similar)

(1) CD = CD (common side of both the triangle)

(2) ∠CDA = ∠ CDB = 90 °

( since, ∠CDA +∠ CDB = 180 ° )

(3) AD = DB (as shown in the diagram)

by using the SAS congurence property .

AC = BC

(Corresponding sides of the congruent triangle)

i.e. 2x = 3x - 5

3x -2x =5

x = 5

Hence, the value of x is 5
