Step 1

Let's find out how many acute angles are in a right triangle.

Step 2

To visualize this, let's draw a standard right triangle.

Step 3

First, we know that by definition, a right triangle has exactly one ninety-degree angle.

\text{Right Angle} = 90^\circ

Step 4

We also know that the sum of all angles in any triangle must be one hundred and eighty degrees.

\text{Sum of Angles} = 180^\circ

Step 5

So, if we subtract our ninety-degree angle from the total, the remaining two angles must add up to ninety degrees.

180^\circ - 90^\circ = 90^\circ
