Which type of transformation creates a shape where only the angles are congruent to the original shape? a) translations b) rotations c) reflections d) dilations

Dilations. This is because dilations are a change in size of the shape. However, the angles would stay the same. In the rigid transformations, translations, rotations, and reflections, the size and angles would stay the same.

da freeck kinda math is this just drop out

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
