Show Answer Key & Explanations Step-by-step solution for: Angles in Quadrilaterals Worksheets
To solve the problem of identifying the angles in each quadrilateral, we need to analyze the given shapes and determine their types based on their properties. Quadrilaterals can be classified into several types, such as squares, rectangles, rhombuses, parallelograms, trapezoids, and kites. Each type has specific angle properties that we can use to identify them.

Step-by-Step Solution:



1. Identify the type of each quadrilateral:
- Look at the sides and angles to determine if the quadrilateral is a square, rectangle, rhombus, parallelogram, trapezoid, or kite.
- Use the properties of each type:
- Square: All sides are equal, and all angles are 90°.
- Rectangle: Opposite sides are equal, and all angles are 90°.
- Rhombus: All sides are equal, but angles can vary.
- Parallelogram: Opposite sides are equal and parallel, and opposite angles are equal.
- Trapezoid: One pair of opposite sides is parallel.
- Kite: Two pairs of adjacent sides are equal.

2. Determine the angles:
- For squares and rectangles, all angles are 90°.
- For rhombuses and parallelograms, opposite angles are equal.
- For trapezoids and kites, angles depend on the specific shape and given information.

3. Analyze each quadrilateral in the image:
- Quadrilateral 1: Appears to be a rectangle. All angles are 90°.
- Quadrilateral 2: Appears to be a rhombus. Opposite angles are equal.
- Quadrilateral 3: Appears to be a parallelogram. Opposite angles are equal.
- Quadrilateral 4: Appears to be a trapezoid. One pair of opposite sides is parallel.
- Quadrilateral 5: Appears to be a kite. Two pairs of adjacent sides are equal.
- Quadrilateral 6: Appears to be a square. All sides are equal, and all angles are 90°.
- Quadrilateral 7: Appears to be a parallelogram. Opposite angles are equal.
- Quadrilateral 8: Appears to be a trapezoid. One pair of opposite sides is parallel.
- Quadrilateral 9: Appears to be a rhombus. All sides are equal, and opposite angles are equal.
- Quadrilateral 10: Appears to be a rectangle. All angles are 90°.

4. Write down the angles:
- For squares and rectangles, write 90° for all angles.
- For rhombuses and parallelograms, write the given angles or use the property of opposite angles being equal.
- For trapezoids and kites, write the given angles or use the properties of the shape.

Final Answer:


\[
\boxed{
\begin{array}{c}
\text{Quadrilateral 1: } 90^\circ, 90^\circ, 90^\circ, 90^\circ \\
\text{Quadrilateral 2: } \text{(Depends on given angles)} \\
\text{Quadrilateral 3: } \text{(Depends on given angles)} \\
\text{Quadrilateral 4: } \text{(Depends on given angles)} \\
\text{Quadrilateral 5: } \text{(Depends on given angles)} \\
\text{Quadrilateral 6: } 90^\circ, 90^\circ, 90^\circ, 90^\circ \\
\text{Quadrilateral 7: } \text{(Depends on given angles)} \\
\text{Quadrilateral 8: } \text{(Depends on given angles)} \\
\text{Quadrilateral 9: } \text{(Depends on given angles)} \\
\text{Quadrilateral 10: } 90^\circ, 90^\circ, 90^\circ, 90^\circ \\
\end{array}
}
\]

If specific angles are given in the image, replace the placeholders with the actual values. Otherwise, use the properties mentioned above to determine the angles.
