10

How do you classify a triangle with all angles less than 90°?

Explicación

In Euclidean geometry, interior angles of a triangle always add up to 180°.

Equilateral triangles have all three sides of equal length.

The square of the hypotenuse equals the sum of the squares of the other two sides.

To form a triangle, the sum of any two side lengths must exceed the third.

Isosceles triangles have exactly two equal sides.

Scalene triangles have all three sides of different lengths.

A right triangle contains exactly one right angle (90°).

In an isosceles triangle, the median from the apex to the base is also perpendicular to the base.

An altitude is drawn from a vertex to the opposite side, forming a right angle.

All angles are acute (<90°) in an acute triangle.
