What is a counter example for the statement congruent angles are always vertical angles?
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
True or false Two angles that have the same measure must be congruent?
Yes, this is the definition of congruent angles.Yes, this is the definition of congruent angles.Yes, this is the definition of congruent angles.Yes, this is the definition of congruent angles.
Are two rhombuses always-sometimes or never similar?
Sometimes. Remember, in order for two polygons to be similar, their angles must be congruent, and their corresponding sides must be proportional. In a rhombus, it is always possible for the angles to differ.
If two angles of a triangle are congruent then the sides opposite those angles may not be congruent?
False. They must be congruent.
What is the name of a parallelogram with 4 right angles but not four congruent angles?
4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
What is a counter example for the statement congruent angles are always vertical angles?
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
What is the difference between vertical angles and congruent angles?
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Can vertical angles be complementary?
Vertical angles must be congruent so if they are complementary, they must be 45 degrees to be complementary.
Vertical angles must have?
have the same vertex. be congruent.
Vertical angles must?
C. have the same vertex. done D. be congruent
Congruent polygons may have noncongruent sides but must always have congruent angles?
False.
Congruent polygons may have noncongruent sides but must always have congruent angles.?
false
Angles that are congruent and supplementary must be?
Angles that are congruent and supplementary must be right angles.
If two angles are congruent then they are both right angles?
Not always. If two angles are congruent then they simply have equal measure. They must only be right angles if they are supplementary, that is, they must both add up to 180 degrees.
If two angles are obtuse then they must be congruent.?
Not always because 98 degrees and 140 degrees are both obtuse angles that are not congruent but angles 150 degrees and 150 degrees are both obtuse angles that are congruent.
True or False Congruent polygons may have noncongruent sides but must always have congruent angles?
falce
Are all angles congruent in a rectangle?
Yes, their measures must always equal 90 degrees.
