A "30 60 90 triangle" has that weird name because those numbers are its three angles.
It can't have any angle of "4".
If a triangle has an angle of '4', then it's not a '30 60 90 triangle'.
in a 30-60-90 right triangle, a right angle is always 90 degrees, the smallest angle has a measure of 30 degrees, and the remaining angle measures 60 degrees.
It is a right angle triangle
A right-angle triangle
The third angle is 90 degrees so it is right angle triangle.
It is a right angle triangle because the 3rd angle has to be 90 degrees
in a 30-60-90 right triangle, a right angle is always 90 degrees, the smallest angle has a measure of 30 degrees, and the remaining angle measures 60 degrees.
A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.
It is a right angle triangle
A right-angle triangle
The third angle is 90 degrees so it is right angle triangle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle because the 3rd angle has to be 90 degrees
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
The third angle has to be 90 degrees so it would be a right angle triangle.
That it must be a right angle triangle because the 3rd angle must be 90 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle providing that the 3rd angle is 30 degrees.
