In a $45^\circ$ – $45^\circ$ – $90^\circ$ right triangle, the two legs are—

aequal to the hypotenuse
bequal to each other
cperpendicular only
dunrelated

ব্যাখ্যা

When the two acute angles are both $45^\circ$ , the sides opposite them are equal, so the two legs of the triangle are equal to each other. Such an isosceles right triangle has legs of identical length.
