Are Adjacent angles of a quadrilateral in a circumscribed circle are always supplementary?
False :]
An example that proves that a conjecture or statement is false?
Counter-example
What is an examlpe that proves that a conjecture or statement is false?
A therefore B A is true Therefore B is true Logically..... A is true A is false Therefore B is false
True or false Dilating a triangle changes the angles and side length of the triangle?
False.
Is it true or false that in a parallelogram the opposite angles are complementary?
Generally false. In a parallelogram, the opposite angles are equal. They could be complementary in a highly skewed parallelogram in which one angle is 45 degrees.
How determine whether the conjecture is true or false. If false give a counterexample. Given LMN and XMZ are coplanar. Conjecture The angles are vertical angles.?
Select one: a. False; the angles may be supplementary. b. True c. False; one angle may be in the interior of the other. d. False; the angles may be adjacent.
What are two obtuse angles supplementary true or false?
no because there are 2 kinds of angels-devil angel-good angel
Supplementary angles add to 270 degrees true or false?
False. Supplementary angles add to 180degrees.
If a quadrilateral is a parallelogram then its opposite angles are always supplementary?
False because it will have 2 equal opposite obtuse angles and 2 equal opposite acute angles with the 4 angles adding up to 360 degrees.
True or False- If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
false
A triangle can have two obtuse interior angles true or false?
False
Can both angles in a pair of complementary angles can be obtuse true or false?
yes
If opposite angles of a quadrilateral are supplementary is the quadrilateral a parallelogram?
No. A quadrilateral is a parallelogram when consecutiveangles are supplementary.
Intersecting chords form a pair of supplementary vertical angles?
false
Are Adjacent angles of a quadrilateral in a circumscribed circle are always supplementary?
False :]
Two angles that have a common vertex and a common side are called supplementary angles. T or F?
False
True or false If opposite angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
