19 Quadrilateral PRST is transformed according to the rule (x, y) (x + 9, y + 4) to create quadrilateral PRST.
Which statement is true?
A The side lengths of quadrilateral PR'ST' are twice the corresponding side lengths of
quadrilateral PRST
B The angle measures of quadrilateral PRST'are equal to the corresponding angle
measures of quadrilateral PRST.
C The side lengths of quadrilateral PRST' are 9 units longer than the corresponding side
lengths of quadrilateral PRST.
D The angle measures of quadrilateral PRST' are greater than the corresponding angle
measures of quadrilateral PRST.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
