Assuming the kite has four sides and is not a square, then yes, it must have obtuse angles.
A quadrilateral kite can have two obtuse angles and two acute angles that add up to 360 degrees.
2 obtuse and 2 acute in the classic kite shape.
No.
Yes.
Yes, a kite typically has at least one obtuse angle. A kite is a quadrilateral with two distinct pairs of consecutive, congruent sides. In a kite, the angles between the non-congruent sides (the angles opposite the longer and shorter sides) are usually not congruent. One of these angles can be obtuse, depending on the specific shape of the kite. However, it's important to note that a kite can also have acute angles, but it must have at least one obtuse angle.
A rhombus, parallelogram, kite
A traditional kite shape (a point at the top, then widest about 1/3 of the way down, then tapering to another point at the bottom) has one, two or three obtuse (>90 degree) angles. The two angles at the widest point, about 1/3 of the way from the top, are generally obtuse, but don't have to be. The bottom angle is almost never obtuse. The top angle is sometimes obtuse. So if the top angle is obtuse but the side angles are not, a kite shape has one obtuse angle. If the top angle is not, but the side angles are, it has two obtuse angles. If the top and side angles are obtuse it has three.
parallelogram, rhombus, kite, etc.
Yes as well as 2 acute
No, a trapezoid does not have four obtuse angles. A trapezoid has one pair of parallel sides and the other pair of non-parallel sides. The angles of a trapezoid can be a combination of acute, obtuse, and right angles, but it cannot have four obtuse angles.
The shape that has 4 equal sides, 2 acute angles, and 2 obtuse angles is a kite. In a kite, the two pairs of adjacent sides are equal in length, creating the four equal sides. The acute angles are formed between the unequal sides, while the obtuse angles are formed between the equal sides.
