Yes
true.
Sounds true to me, all three angles are congruent...
this is true
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
Not so. The two acute angles of a right triangle must add up to 90 degrees.So if the triangles have one congruent acute angle in common, they must alsohave the other acute angle in common, and then they're similar.
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.
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.
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
A scalene triangle can have an obtuse angle and two different acute angles.
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.
The hypotenuse angle theorem, also known as the HA theorem, states that 'if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.'
