What else can I help you with?
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?
Parallelograms have 2 acute and 2 obtuse angles, or 4 right angles in the case of a rectangle. But either way, the max number of acute angles is 2 and the minimum is zero. Remember acute angles is less than 90 degrees so in a square or rectangle, which is a parallelogram since it has two sets of parallel sides, there are NO acute angles. So the answer to the question is..it depends, but no more than two for sure.
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
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
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
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
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.
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 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.
