What is an example of definition by negation?
Definition by negation is a solution to a right angle statement.
What is the negation of the statement quadrilateral abcd is a paralleogram and it has a right angle?
"abcd is not a parallelogram or it does not have any right angles." ~(P and Q) = ~P or ~Q
What does counter example mean in geometry?
if you are doing proof statements...there is converse which is where you flip the statement around so if the statement would be IF a angle measures 90 degrees, THEN the angle is a right anlge. The converse would be IF a angle is a right angle, THEN it is 90 degress. THE COUNTEREXAMPLE would be if the statement was false you would say or show a picture of something defining that statement
How are straight angle's different from right angles Is this a statement?
A straight angle is an angle that is 180 degrees exactly (a straight line). A right angle is 90 degrees (like the corners of a square.)
How do you prove a right angle triangle?
You cannot prove "a right angle triangle". You may or may not be able to prove statements about right angled triangles but that will depend on the particular statement.

What is the negation of angle a is a right angle?
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
What is true about the statement if two angle's are right angle's then the two angle's have an equal measure and its converse If two angle's have an equal measure then they are right angle's?
what statement about the two angles in a right tringle that do not measure 90 is true

What must true statement about a 30 angle and 60 angle triangle?
That it must be a right angle triangle because the 3rd angle must be 90 degrees

Is this statement true or falseThe sum of the angle measures of two right angles is equal to the measure of a straight angle.?
true
Which statement is a true statement about isosceles right triangle?
That it has a 90 degree angle and two equal 45 degree angles
Is this statement true or falseThe two sides that form the right angle in a right triangle are called legs?
true
A certain triangle has a 30 angle and 60 angle which must be a true statement about the triangle?
The longest side is twice as long as the shortest side.
