Which statement is true? 1. All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.

2. Only some squares are rectangles. Rectangles have 4 sides that are the same length. Therefore, only some squares have 4 sides that are the same length.

3. Only some squares are rectangles. Rectangles have 4 right angles. Therefore, only some squares have 4 right angles.

4. All squares are rectangles. Rectangles have 4 sides that are the same length. Therefore, all squares have 4 sides that are the same length.

Not 100% sure but I believe it might be 1. I hope it helps if not let me know.

Explanation:

If you cut a rectangle in half what would you get? A Square! Tbh I learned this is 5th grade and simply just haven’t forgotten. A square is a rectangle however, a rectangle is not a square.

Hope this helped, good luck!

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
