A triangle with two acute angles must be a right angle?
No. The three angles in a triangle, in plane Euclidean geometry, must add to 180 degrees. Acute angles are less than 90 degrees. Therefore you may have a triangle with three angles which are 60 degrees for instance.
If a parallelogram has one right angle then all of its angles must be right?
Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.
A triangle with one obtuse angle must have also have two acute angles true or false?
True and all 3 angles must add up to 180 degrees.
What shapes do not have any right angles or angles greater than a right angle?
Acute triangles. They can have three angles, all less than 90 degrees (total is 180 degrees).Shapes with more than three sides must have angles of 90 degrees or more because the total of their angles must be 360 degrees (quadrilaterals) or more.
Can a triangle have 3 90 degree angles?
No, the interior must add up to 180 degrees, which is two 90 degree angles. A triangle must have three angles, which means it may only have one 90 degree angle. The other two must each be less than 90 degrees.
Verticle angles must be what?
Vertical, possibly!
Angles that are congruent and supplementary must be?
Angles that are congruent and supplementary must be right angles.
Which type of angles must be congruent?
Equal angles.
Triangles must have angles but this figure has no angles whai is it?
A circle.
Is it true If two angles are complementary then both angles must be acute?
True because both angles must add up to 90 degrees
What figure has 4 faces 8 edges 5 verticles?
Apart from the fact that there is no such word as verticle, there cannot be a solid that meets the above description. According to the Euler characteristic, simply connected polyhedra must satisfy:Faces + Vertices = Edges + 2Apart from the fact that there is no such word as verticle, there cannot be a solid that meets the above description.

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.
If two lines intersect then the vertical angles must be?
Equal 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.
Which polygon has more than 5 verticles?
There is no such word as verticle. A polygon with more than 5 vertical sides must have at least 11 sides.
If two lines intersect then the vertical angles formed must be?
Equal angles.
