Answer 1

Yes. The sum of angels on atriangel is always 180. The last angel on the first triangle is 180 - 69 - 43,4 = 67,6 and the last angle on the second triangle is 43,4 so both are same shape.

Answer 2

No because you're only given the angles and AA doesn't exist

Answer 3

The answer is yes... if you need to  know why..AAA the three angles equl eachother

Answer 4

Yes by AA

Answer 5

hi

two angles are given now you can find the third angle,ie 180 - sum of two angles and check for aaa

:)

Answer 6

Yes, by AA.

All of the angles have the same measures for both triangles, based on figuring out the unknown angle for each triangle based on the angles adding up to 180 degrees (subtracting the total of the two known angles from 180).

Answer 7

ANS: (a) yes, by AA

it can be proved by AA similarity, becauz by angle sum property all the angles will be equal.

* in the 1st triangle the third angle will be 180-(69+43.4) = 67.6, which same as the third angle in the - second triangle

* thus all angles r equal, hence AA similarity.

* AA similarity is the same as AAA similarity.
