Which triangle has 0 reflectional symmetries? A triangle has all different side lengths and angle measures. A triangle has all equal side lengths and angle measures. A triangle has 2 equal side lengths and 2 equal angle measures. A triangle has 2 equal side lengths and 2 equal angle measures.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
