All the angles are smaller than 90o, so triangle is acute triangle.

The triangle with angles measuring 50 degrees, 65 degrees, and 65 degrees is an isosceles triangle. In an isosceles triangle, two of the three angles are equal, making it a special type of triangle. In this case, the two angles measuring 65 degrees are equal, indicating that the two sides opposite these angles are also equal in length.
A triangle with angles that measure 30, 60, and 90 degrees is a special type of right triangle known as a 30-60-90 triangle. In this triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle. This relationship is based on the properties of trigonometry and the ratios of the sides in a 30-60-90 triangle.
With any type of triangle, the angles add up to 180 degrees. It does not matter if it is equilateral, scalene, or acute, or even right, obtuse, or acute.
This is a SCALENE triangle. There several types of triangle; Equilateral ; The three sides are the same length and the three angles are ALL 60 degrees. All angles are ACUTE Isosceles ; Two sides are the same length , and two angles have the same degree value. . May be ACUTE or OBTUSE. Right angled ; The three sides may vary in length, but ONE angle is 90 degrees. Is ACUTE, and maybe ISOSCELES. Scalene ; All three sides are of different length, and all three angles have different degree value. May be ACUTE or OBTUSE. Fort ALL triangles , of whatever shape, the sum of the interior angles is ALWAYS 180 degrees.
Oh, dude, a pentagon with 2 obtuse angles, 2 right angles, and 1 acute angle? That's like a shape having an identity crisis. Technically speaking, a pentagon can't have those angles, but hey, if that's the kind of rebellious shape you want to hang out with, who am I to judge?
