Which of these rotations will map an equilateral triangle to itself?(1 point) 45°

60°

90°

120°

120°

Step-by-step explanation:

The equilateral triangle is the triangle that has three sides equal also they are congruent to each other and each side has an angle of 60 degrees

Now for rotation it would be a map to itself at 120 degrees counterclockwise

So the same is to be considered

Hence, the last option is correct

And, the other options are incorrect

three-fourths of an hour

36÷48=0.75

0.75=

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
