HELP ME!!! quick i need this done by tomorrow!?!?!?

Question

ok, it says you can turn around if-then statements. This sometimes changes the meaning of a statement. Rewrite each of the following statemenst and determine if the result is still a true statement.
20) If a quadrilateral is a parallelogram, then it has two pairs of opposite sides that are parallel.
22) If a triangle is equilateral, then it is an isosceles triangle.


thanks so much!! =)

Answer 1

20) If a quadrilateral has 2 pairs of opposite sides that are parallel then it is a parallelogram. True

22) If a triangle is isosceles then it is equilateral. False.

Answer 2

If its due tomarrow, then you should have done it when it was assigned lazy butt. Lol. I probably did this wrong and I'm in AP Pre-Calculus lol. Well check it before you automatically copy it okay? Laterz..

20) If the two pairs on the opposite sides of a quadrilateral are parallel, then the quadrilateral is a parallelogram.
22) If a triangle is an isosceles, then it is an equilateral.

The first statement sounds correct but not the second. Well let me know what the answers were after you find out k?

Answer 3

20. A parallelogram is a quadrilateral and has two pairs of opposite sides that are parallel. True statement.
22. A triangle is an equalateral and is an isosceles triangle. Not true.

Answer 4

20) If a quadrilateral has two pairs of opposite sides that are parallel, then then it is a parallelogram. (true)

22) If a triangle is isosceles, then it is an equilateral triangle. (false)

An equilateral triangle has all of it's sides and angles equal, whereas, an isosceles triangle has tow sides and 2 angles equal. An equilateral triangle is isosceles but an an isosceles triangle is not equilateral.

Answer 5

20) If a quadrilateral has two pairs of opposite sides that are parallel, then it is a parallelogram. TRUE

22) If a triangle is an isosceles triangle, then it is equilateral.
Sometimes.

Answer 6

Both true

parallelogram has both opposite sides parallel

isosceles triangle has 2 equal sides
equilateral triangle has 3 equal sides
so if 3 sides are eqqual, it would also be a triangle with 2 equal sides

Answer 7

if a triangle is isosclets it is equilateral

if a quad has two pr of opp side prl then its a parallogram

one is always true and one is sometimes true
