the proportion is 1:1 with one another, and because it’s a right triangle, the proportion of the hypotenuse is 1:√2 with either of the other sides. The equal proportions tip you off that the sides are 1, 1, √2, which belongs only to the 45-45-90 special triangle. To find the...
Label the triangle "isosceles" if only two sides are equal. Remember that the angles contained by the two equal sides (the base angles) will be equal to each other. So, if you know one base angle in an isosceles triangle, you can find the other two angles. For example, if one angle...

The triangle's hypotenuse is the radius of the unit circle; one of its legs is on thex-axis; and the other leg is parallel to they-axis. You can see what this 30-60-90-degree triangle looks like in the figure. Find the length of the hypotenuse. ...
