What is an angle that is exactly 90 degrees?
geometry
Why is it impossible for a triangle to contain 180 degrees?
The opposite is in fact true; the total internal angles of all triangles is exactly 180 degrees.
Are all isosceles triangles with two 50 degrees and exactly one side of length 10cm congruent?
Yes, they are.
What phrase does SAS represent in geometry?
If any two sides of a triangle are equal in length to two sides of another triangle and the angles between each pair of sides have the same measure, then the two triangles are congruent. AKA the triangles are exactly the same size. (SAS stands for Side Angle Side.)
If using exactly two triangles what shape will that make?
The two triangles would make either a square or a rectangle.

What is a straight line in geometry?
an angle that measures exactly 180 degrees
Can the sum of the angles of a triangle exceed 180 degrees?
In basic Euclidean geometry no, the sum of the angles always equals 180 degrees exactly. In non-Euclidean geometry it can exceed 180 degrees.

Yes, they are.
What do you look for if you want to classify a triangle?
Classifying triangles is a great skill to know.Acute Triangles: These are triangles with measures lessthan 90 degrees.Obtuse Triangles: Any triangle with measures greater than 90 Degrees.Right Triangle: Any triangle with a Right Angle (exactly 90 degrees)
How many different isosceles triangles have at least one angle that measures exactly 20?
If one angle measures 20 degrees then the other two angles must each measure 80 degrees and many other similar or congruent isosceles triangles can have the same interior angles.
What is triangle and who many types of triangle?
A triangle is a 2-dimensional closed shape (called a polygon) with 3 sides. The three sides form a closed shape with three interior angles, hence the name "tri-angle." There are three general types of triangles: they are called Acute, Obtuse, and Right Triangles. Acute Triangles contain interior angles that are all less than 90 degrees. Obtuse Triangles contain one (and only one) interior angle that is greater than 90 degrees. Right Triangles contain one (and only one) angle that is exactly 90 degrees. There are also sub-types of triangles; the most common sub-types are Equilateral and Isoscles Triangles. The interior angles of Equilateral Triangles are all 60 degrees. At least two interior angles of Isoscles Triangles are equal to each other.
Is there such thing as a right obtuse angle?
No. Right triangles are triangles with one angle exactly 90°, and obtuse angles are triangles with exactly one angle that is greater than, but not equal to, 90°.

What has exactly 5 vertexes?
a pyrimad in geometry.
Are all isosceles triangles with two 50 degrees angles and exactly one side of length side 8 cm?
Yes and the equal sides will each be 6.222895307 cm in length with a apex angle of 80 degrees
