Are vertical angles congruent or supplementary angles?
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
Is two acute angles are always complementary?
No
If two sides of a triangle are congruent then the angles opposite those sides are congruent?
always
Two congruent angles are angles that have what?
Two angles that are congruent have the same angle measurement.
How many acute angles are in a parallelogram?
Well, honey, a parallelogram has a grand total of zero acute angles. It's all about those congruent opposite angles being the same size, which means they're either both obtuse or both acute. So, if you're looking for acute angles, you better go find yourself a different shape to play with.
What are two angles with the same measure?
acute
Can two acute angles be congruent?
yes
Does obtuse triangle have any angles congruent?
An obtuse triangle must have two acute angles and these can be congruent.
What is a shape with four congruent sides two acute angles and two obtuse angles?
it is a rhombus
Which types of angles are always congruent?
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
Two right triangles are similar if the acute angles of one triangle are congruent to the acute angles of the other triangle?
yes there similar
I have four congruent sides two obtuse angles two acute angles and two pairs of parallel sides. What am I?
A parallelogram
What is a quadrilateral with all congruent sides with two obtuse and two acute angles?
It is a rhombus
If two congruent angles form a supplementary they are acute angles.?
Not true because supplementary angles add up to 180 degrees and two acute angles would be less than 180 degrees.
Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
Are vertical angles congruent or supplementary angles?
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
What is a triangle with all acute angles and exactly two congruent sides?
By Definition, a triangle with two Congruent Sides is an Isosceles Triangle. For ALL angles to be Acute, that is, LESS than 90o , the two opposite angles must be greater than 45o. Remember that the SUM of the angles in a Triangle must equal 180o.
