Answer 1

Если в треугольнике один угол прямой, то треугольник называется прямоугольным. Соответственно остальные углы треугольника острые.

Answer 2

Determining the Type of Triangle with Two Acute Sides and One Right Angle

When a triangle has two acute angles and one right angle, it is classified as a right-angled triangle.

This can be determined based on the characteristics of the angles in the triangle. In a right-angled triangle, one of the angles is a right angle, which measures 90 degrees, while the other two angles are acute, meaning they are less than 90 degrees.

The relationship between the angles in a right-angled triangle can be expressed using the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Therefore, based on the given information of two acute sides and one right angle, the triangle in question is a right-angled triangle.
