Nope...there are always two acute angles in a right triangle, and they can be congruent or not. If the triangle is isoceles, then (and only then) they are congruent.

I think you mean "complementary" where their measures always add up to 90 degrees. (Reason: the sum of all three interior angle measures in a triangle equals 180. So in a right triangle, where the right angle measures 90, this leaves 90 degrees for the other two angle measures together.)
These two acute angles are only congruent when each measures 45 degrees, when the two sides are congruent and you have an isosceles right triangle. If the two sides are different lengths, the angles will have different measures and will not be congruent but will always be complementary.

Hi, congruent means equal. So the answer is no, you can have a right triangle with one 90 degree angle ( of course ) and two other angles that are not equal. To follow the rules however, the other two angles will have to add up to 90 degrees. Because........all triangles have to have a total of 180 degrees when all three angles are added up !! ChasD

Not always. I assume you mean a flat triangle. It's possible to have a triangle where the angles total more than 180 degrees if you draw it on the surface of a sphere.

Wow... maximum of incorrect solutions it somewhat is the ideal suited answer -if 2 triangles are congruent are they comparable? definite -is an obtuse triangle resembling an acute attitude? NO (by no potential) -are 2 top triangles comparable? NO (from time to time they are) -are 2 equilateral polygons comparable? NO (from time to time they are) -are 2 rectangles comparable if neither is a sq.? NO (from time to time they are) ===== Luvkitty is real, additionally ==== Cheeze... youre a similar dicckwad you ever have been. I didnt reproduction your solutions. yet effective attitude... via employing accusing me of doing so which you have earned your self "factors". no longer which you fairly desire them... we the two understand while this submit is going up for a vote, all twenty of your reproduction debts will vote you BA. If youre dumb adequate to certainly question why our posts look so comparable, its by using fact we the two replica-pasted from the POSTER. And, I take place to understand which you replaced your solutions after your unique submit... from incorrect to top... merely after being further on by employing others' solutions.
