What must true statement about a 30 angle and 60 angle triangle?
That it must be a right angle triangle because the 3rd angle must be 90 degrees
A triangle has a right angle if and only if it is a right triangle?
yes. a right triangle must have one angle that measures 90 degrees
If a triangle has one acute angle is the triangle necessarily acute?
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
What kind of triangle has an angle with 100 degrees and 50 degrees?
The third angle must be 30 degrees so it is an obtuse triangle
Is a 56 ft 65 ft 16ft triangle a right angle triangle?
The ratio of the length of the side of a right angle triangle must be 3,4,5 16,56,65 are not in that ratio.

The fiqure must have at least one right angle angle?
triangle
What triangle isangle 50 and angle 70?
The third angle must be 60 degrees so it is a scalene triangle
Is it possible to draw a triangle with an acute angle and an obtuse angle?
Yes. Every triangle with an obtuse angle must have two acute angles.
Why not left angle triangle but right angle triangle?
Because the phrase 'right angle' indicates 90 degrees whereas there is no such angle as a 'left angle'
What is the thirty degree sixty and degree right triangle theorem?
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
What is a shape that must be a 90 degrees angle?
A right angle triangle must have a 90 degree angle and two acute angles.
In order to circumscribe a circle about a triangle the circle's center must be placed at the incenter of the triangle.?
This statement is incorrect. To circumscribe a circle around a triangle, the circle's center must be located at the circumcenter, not the incenter. The circumcenter is the point where the perpendicular bisectors of the triangle's sides intersect, while the incenter is the point where the angle bisectors meet and is the center of the triangle's inscribed circle.
If a triangle has one acute angle is the triangle necessarily acute?
No, an acute triangle must have all 3 angles under 90 degrees. A triangle can have an acute angle and still be a right triangle or an obtuse triangle.
Can a triangle have an acute angle?
Yes it can. A triangle must have at least two acute angles.
