right triangle. obtuse triangle. acute triangle
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees.
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
30"x60" and 45"
Equilateral: 3 equal sides and 3 equal angles Isosceles: 2 equal sides and 2 equal angles Right angle: a 90 degree angle and 2 acute angles and sides that vary in length Obtuse: an obtuse angle and 2 acute angles and sides that vary in length Scalene: 3 acute angles and 3 different side lengths

Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees.
equaladiral triangle: all sides are equal in size scalene triangle: all sides are different in size isosceles triangle: two sides are the same length in size
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.

equilateral triangle has all angles of 60 degrees isosceles triangle has only two equal angles scalene triangle have no equal angles acute triangle has all angles less than 90 degrees right angle triangle has one angle of 90 degrees obtuse triangle has one angle greater than 90 degrees right isosceles triangle has 90, 45, 45 degree angles assuming two angles are the same: acute isosceles triangle can range from <90,>45,>45 down to >0,<90,<90 obtuse isosceles triangle can range from >90,<45,<45 up to <180,>0,>0
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
Equilateral, isosceles and scalene.
30"x60" and 45"
Equilateral: Length of all 3 sides is equal.Isosceles: At least 2 sides have equal length so an Equilateral triangle is also an Isoceles triangle.Scalene: The lengths of all sides are different.
Equilateral: 3 equal sides and 3 equal angles Isosceles: 2 equal sides and 2 equal angles Right angle: a 90 degree angle and 2 acute angles and sides that vary in length Obtuse: an obtuse angle and 2 acute angles and sides that vary in length Scalene: 3 acute angles and 3 different side lengths
