Can a triangle have 1 obtuse angle and 2 acute angles?
A triangle can have one obtuse angle and two acute angles. The sum of all three angles must equal 180 degrees.
What shape has 1 acute 1 obtuse 1 right angle?
The shape that has 1 acute angle, 1 obtuse angle, and 1 right angle is a scalene triangle. In a scalene triangle, all three angles are different, so it is possible for one angle to be acute (less than 90 degrees), one angle to be obtuse (greater than 90 degrees), and one angle to be a right angle (exactly 90 degrees). This unique combination of angles makes the scalene triangle a versatile geometric shape.
Is an equilateral triangle be an obtuse triangle?
No, an equilateral triangle can not be an obtuse triangle. All angles in an equilateral triangle are 60o. An obtuse triangle has 1 angle that is greater than 90o.
What shape has 1 right angle 2 acute angles and 1 obtuse angle with 4 side and 1 set of parallel lines?
No shape does. If it has 4 sides and one pair of parallel lines it cannot have only 1 right angle, it must either have: 1) 2 right angles, 1 acute acute and 1 obtuse angle; or 2) no right angles, 2 acute angles and 2 obtuse angles; in which case it would be a trapezium (trapezoid).
Can a triangle have 1 obtuse angle?
A triangle can only have 1 obtuse angle. Obtuse - greater than 90 degrees. Since a triangles 3 angles add up to 180 degrees, only 1 angle can be obtuse. Right triangle 90 degrees and 2 - 45 degree angles. Perfect? triangle has 3 - 60 degree angles.
