D does not answer the question!
Oh sorry I meam two angles that are complementary have s sun of 45
Yes. That is the untrue statement.
Which statement is true?
A.Two angles can be complementary and equal.
B.Two angles cannot be equal if they are complementary.
C. An angle can be complementary only if it is 90°.
D. Only three angles can be supplementary.
To figure out which statement is not true, we need to understand the definitions of "supplementary" and "complementary" angles.
Supplementary angles are two angles that add up to 180 degrees. So if we have angle A and angle B, and they are supplementary, then A + B = 180 degrees.
Complementary angles, on the other hand, are two angles that add up to 90 degrees. So if we have angle C and angle D, and they are complementary, then C + D = 90 degrees.
Now, let's examine the two statements:
1. "Two angles that are supplementary have a sum of 180." This statement is true because the definition of supplementary angles is that they add up to 180 degrees. So, statement 1 is true.
2. "Two angles that are complementary have a sum of 45." This statement is not true because the definition of complementary angles is that they add up to 90 degrees, not 45. Therefore, statement 2 is not true.
In summary, the statement that is not true is: "Two angles that are complementary have a sum of 45."
