Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
Do all triangles have two acute angles?
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
How many acute angles does the letter y have?
It has one acute angle as y and one obtuse angle with both angles adding up to 180 degrees
What is One way obtuse triangles and acute triangles are different?
One way is they both are triangles and have 3 sides.
How many acute angles can be in a quadrilateral?
A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)
Can a triangle be both acute and obtuse?
No, because if there is on obtuse angle the triangle will always be obtuse.
Does a parallelogram have 2 acute and 2 obtuse angles?
both
What do acute triangles and obtuse triangles have in common?
they are both angkes
Does a trapezium have acute angles or obtuse?
It can have a mixture of both acute and obtuse angles providing that the 4 interior angles add up to 360 degrees.
How is acute and obtuse angles alike?
They are both angles.....acute is smaller than ninety degrees and obtuse is larger/wider. They aren't alike in a lot of ways though.
The sum of two acute angles is something always or never an obtuse?
The sum of two acute angles is sometimes an obtuse angle because, acute angles can measure from 10 to 90 degrees. Two 30 degree angles would both be acute whose sum would only create another acute angle of 60 degrees. But, two80 degree angles would both be acute angle whose sum would only create an obtuse angle.
If two angles of a parallelogram are acute what can you conclude about the other two angles?
If two of the angles of a parallelogram are acute, then the other two angles will be obtuse. Since a parallelogram contains two pairs of parallel sides, both of the acute angles and both of the obtuse angles respectively will measure the same.
Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.

Also for an acute triangle, it would have 3 acute angles.
Are an obtuse and acute angles supplementary?
If they both add up to 180 degrees then they are supplementary angles.
When you use the protractor do you use the top numbers or the bottom numbers?
You use both. An acute angle [ /_ or _\] is less than 90 degrees - directly on top. An obtuse angle is [ \_ or _/ ] is greater than 90 degrees. You use both. An acute angle [ /_ or _\] is less than 90 degrees - directly on top. An obtuse angle is [ \_ or _/ ] is greater than 90 degrees. You use both.

Explain Why an angle that is supplementary to an acute angle must be an obtuse angle?
If x is acute, then x < 90 and -x > -90. Adding 180 to both sides, 180-x > 90, i.e. the supplement of x is obtuse.
