Answer 1

Answer:

1) Two triangles

Explanation:

2) AB=CD (given)

BD (common)

AD = BC(given)

By SSS congruency they are congruent

3) Angle A=C

by CPCT as triangle ABD congruent to triangle CDB

Answer 2

Answer:

1. There are 2 triangles in the figure

2. Consider triangle ABD and CDB.

AB = CD (given)

AD = BC ( given)

BD = BD (common)

By SSS (side side side) Congruence rule ,the triangles ABD and CDB are equal

Triangle ABD is congruent to triangle CDB

3. By CPCT, ( Corresponding Parts of Congruent Triangles ) angle A is equal to angle C
