Is it true that AAA angle-angle-angle does not guarantee congruence between two triangles?
The answer is no. When two triangles are congruent all three corresponding sides are the same and all three corresponding angles are the same. Two triangles with the same corresponding angles can have corresponding sides different so they are not congruent.
How many degrees are in equilateral triangle?
In an equilateral trianger, each angle is 60 degrees. In all triangles, including equilateral triangles, all 3 angles add up to 180 degrees.(the above assumes Euclidean - flat - space. In Hyperbolic space there are less than 180° in all triangles; in Spherical space more than 180° in all triangles)
Do all triangles have at least 1 right angle?
only right tringles or HL triangles have at least 1 right angle
Do all right triangles have acute angles?
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
Can Pythagorean Theorem be used on all types of triangles?
No it can only be used with right angle triangles.

Finding measurements of triangle only given one angle measurement?
Not possible. There are an infinite number of triangles that all have that same one angle in them.
What are the properties of similar triangles?
2 sides in same ratio and included angle all angles 3 sides in same ratio Triangles are similar if they are the same shape, with the same angles and proportions, but not necessarily the same size.
What kind of triangles does the Pythagorean theorem work for?
All right angle triangles
How many degrees does an equilateral triangle?
180 degrees all triangles have 180 degrees.(the above assumes Euclidean - flat - space. In Hyperbolic space there are less than 180° in all triangles; in Spherical space more than 180° in all triangles)
Do all triangles have the same angle measurements?
No. But their three interior angles will always add up to 180 degrees.
Do all triangles have at least 1 right angle?
only right tringles or HL triangles have at least 1 right angle
What does a triangle look like?
There is alot of triangles. Triangles are three sided two slanted lines connected with a straight line on the bottom. The types of triangles are is the Isosceles, Acute, Right (angle), Left (angle), Equilateral, Obtuse, and Scalene triangles.A triangle has equilateral sides all around that are the same length and same angles.
What size and shape do two congruent triangles have?
to be congruent two triangles have, ASA-two angles the same with a side length between them. SAS-two side lengths the same and a same angle between them. SSS-all 3 side lengths the same. RHS-if the triangles are right angles ,and the hypotenuse are the same. :)
Do all right triangles have acute angles?
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
Are all 30-60-90 triangles isosceles?
No because 30-60-90 triangles are right angle triangles
