Which 2-D shapes can have 2 acute angles and 2 obtuse angles?
With 2 acute and 2 obtuse angles it has 4 angles - the shape is a quadrilateral. The shape can be one of trapezium, parallelogram, rhombus, kite or a general quadrilateral. With the two acute angles next to each other (forcing the two obtuse angles to be next to each other) the shape can be either a trapezium or a general quadrilateral.
Does a rhombus have 4 acute angles?
No, only 2 the other 2 are obtuse
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
What has two pairs of parallel sides may have two acute angles of the same and two obtuse angles of the same?
The shape you are describing is a trapezoid. A trapezoid has two pairs of parallel sides, with one pair longer than the other. It can have two acute angles and two obtuse angles, depending on the lengths of the sides. The acute angles are typically smaller than 90 degrees, while the obtuse angles are larger than 90 degrees.
Given two parallel lines with a transversal if one of the angles measures 50 degrees what are the measures of all the other angles?
All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.
