Answer 1

not compelete question

Answer 2

Answer:

3cm

Step-by-step explanation:

Given:

AACB and AADB are two congruent right - angled triangles on the same base.

AB= 6 cm

AC = 3 cm

To find:

BD = ?

Solution:

In AACB and AADB, we have:

AB=AB (common)

BC = AD. (given,the triangles are congruent, in addition to this, their corresponding sides are of equal length.)

Angle ACB = Angle ADB (each 90°)

so, the triangles are congruent.

=> AC = BD (by cpct) => 3cm = BD

So, BD = 3cm.

hope this helps you.
