Using a protractor which should give a measure of a 90 degree angle and two acute angles that add up to 90 degrees.
By using trigonometry that is applicable to a right angle triangle.
If it is a right triangle, you can use the Pythagorean Theorem. If you know the angle measures, you can use cosine/sine/tangent.
The Pythagorean theorem might be of use.
To solve this, use the fact that the sum of all three angles, in a triangle, is 180 degrees.
Use Pythagoras: 24 units
drop a line from the vertex to the bottom line of the triangle you get a right angle triangle with side 6, 3 and x where x is the altitude of the triangle 6^2=3^2+x^2 use pythagoreus theorem 36=9+x^2 x=sqrt 27=3sqrt3=5.196cm
Use a protractor.("'\(o.o)/"') heheh deal with it!
Pythagoras's Theorem is used to determine if a triangle is a right triangle or not.
any right triangle
To circumscribed a circle about a triangle you use the angle. This is to get the right measurements.
Use the information about the right triangle that you're given, together with all of the things you've learned that are true about every right triangle.
A right triangle.
