Don't be obtuse... You can't.
As you may recall the sum of the interior angles in any triangle is 180 degrees.
The definition of an acute angle is an angle less than 90 degrees.
If only one angle in a triangle is less than 90 degrees, the other two must therefore be 90 degrees or more, and their sum would then be 180 degrees, or more. For the sum of all three to be exactly 180 degrees, the acute angle would have to be 0 degrees or less, and the practical effect of that observation is that it can't exist.
What else can I help you with?
Can you draw a triangle that has just one acute angle?
no, it is impossible
If one angle in a triangle is acute can the other two angle also be acute?
Yes. In this case a triangle is called an acute triangle.
What is the difference between a right an acute and obtuse triangle?
A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)
How many acute angles does an acute triangle have?
One acute angle
Is it possible to draw a triangle with exactly one obtuse angle?
Yes providing that the other two angles are acute
Is it possible to draw a triangle that has only one acute angle?
no
Can you draw a triangle that has just one acute angle?
no, it is impossible
If a triangle has one acute angle is the triangle acute?
yes, it only needs one acute angle out of the three to make it an acute triangle.
If one angle in a triangle is acute can the other two angle also be acute?
Yes. In this case a triangle is called an acute triangle.
How do you bisect an obtuse angle?
In the same way that you bisect an acute triangle. Alternatively, you could extend one of the rays of the obtuse angle so that you have an acute angle. Bisect that angle and then draw a perpendicular to the bisector of the acute angle through the vertex.
How do you draw an obtuse scalene triangle?
One angle must be an obtuse angle and the other two angles must be acute angles
What is the difference between a right an acute and obtuse triangle?
A right triangle has one angle a right angle (90o) An obtuse triangle has one angle an obtuse angle (> 90o) An acute triangle has all angles acute (< 90o)
Are two right triangle similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes
How can you determine if a triangle is acute obtuse or right triangle?
If all of the angles in a triangle are acute then it is an acute triangle. If one angle is right (or 90 degrees) then it is a right triangle. If one angle is obtuse then it is an obtuse triangle.
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 you draw an obtuse triangle?
Yes, its a triangle that has one obtuse angle (an angle over 90 degrees) and two acute angles (angles that are les that 90 degrees).
How many acute angles does an acute triangle have?
One acute angle
