Determine the truth value of the conjecture. if it is false, provide a counterexample. conjecture: all squares are rectangles. a. true b. false; a square with side length 8 is not a rectangle c. false; no counterexample needed d. false; no squares are rectangles

A. true

Step-by-step explanation:

Conjecture: All squares are rectangles. This is true.

Every square is a rectangle because it is a quadrilateral with all four right angles.

But every rectangle is not a square, because to be a square its sides must have the same length.

Hence, the answer is true.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
