Question

By which rule are these triangles congruent? A) AAS B) ASA C) SAS D) SSS

Answer 1

it would be SSS...

Explanation:

Its meaning is "side side side''... so you see how the triangle, ABD has the dashed (same number of lines) through the lines of the triangle, it means the sides are all congruent meaning that the sides are the same

Answer 2

The triangles are not congruent.

Explanation:

The triangle ABD is an equilateral triangle, then all their sides are equal and all the angles are equal to 60º. Then x=60º and y=30º (because the sum of the internal angles of a triangle have to be 180º)

Then we can conclude that the triangles are not congruent because they share two sides, but does no have any angle in common, as we can see in the next list of the angles.

• Triangle ABD

angle ADB= angle ABD= angle DAB=60º

• TriangleBCD

angle BDC=30º

angle DCB=30º

angle CBD=120º
