Equilateral triangle = All sides congruent Scalene triangle = No sides congruent Isosceles triangle = At LEAST two sides congruent Right triangle = Triangle with one right angle Obtuse triangle = Triangle with ONE obtuse angle Acute triangle = Triangle with ALL acute angles

If the hypotenuse and an acute angle of a right triangle are congruent to the correspondingparts of another right triangle, then the triangles are congruent.

Yes.

That is simply called a right triangle.

A right isosceles triangle.

A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.

A scalene right triangle is a triangle that has no congruent sides and and one right angle.

The leg-angle congruence theorem says if one leg and an acute angle of one right triangle are congruent to one leg and an acute angle of another right triangle, then the two right triangles are congruent.

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.

The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
