No. That's a good number for ALL triangles,
no matter what their shape or size may be.

Which one is incorrect for two triangles to be congruent?
If two angles are equal in measurement then they are congruent as for example the interior angles of a square are congruent because they are all right angles.
What does the interior angels equal in a triangle?
180 degrees. If you think about it, two triangles when put together make a rectangle/square, which has four right angles (90 degrees), so 90 x 4 = 360 degrees, which is the total interior angles of two triangles, so 360 / 2 = 180 for the interior angles of one triangle.
What shape does triangles make?
Triangles can make various shapes depending on their sides and angles. Some common shapes formed by triangles include equilateral triangles (with three equal sides), isosceles triangles (with two equal sides), scalene triangles (with no equal sides), and right triangles (with one 90-degree angle).
Which is not a way to prove two right triangles are congruent ll or ha or hl or AA?
aa. If the angles are equal and the triangles are right triangles, then all three angles are equal, but the sides can grow or shrink, as long as they remain proportional.
Classification of triangles according to the interior angles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees:- Right angle triangle has a 90 degree angle and 2 acute angles Scalene triangle has 3 different acute angles Obtuse triangle has 1 obtuse angle and 2 different acute angles Isosceles triangle has 2 equal angles and a 3rd angle that all add up to 180 degrees Equilateral triangle has 3 equal 60 degree angles
What are triangles that have equal corresponding angles?
Isoceles triangles and right triangles have 2 corresponding equal angles three equal corresponding angles are equilateral triangle

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.

What is the direffece beween a parallelogram anda rectangle?
The main difference is that a parallelogranm has 2 interior equal obtuse angles and 2 interior equal acute angles whereas a rectangle has 4 equal interior right angles

Are a rectangle's angles equal?
Yes; a rectangle has 4 interior right angles.
What are similarities of isosceles and equilateral triangles?
-- Both have three sides.-- Both have three angles.-- Sum of interior angles of both is 180 degrees.-- Both have at least two equal sides.-- Both have at least two equal angles.-- Neither has any right angle.-- Both have at least two acute angles.
What is a best description for each triangle angles?
All triangles have 3 interior angles that add up to 180 degrees and they are made out of acute angles, right angles and obtuse angles.
Are all isosceles triangles right triangles?
No, only one is and it is known as a 'right isosceles triangle'. By definition an isosceles triangle has two equal sides and two equal angles. If those two equal angles are 45o then the third angle must be 90o.
