![**The quadrilateral below is a kite. Find the missing measures.**
![Diagram of a kite-shaped quadrilateral KETE](URL to educational website image)
In the given diagram, the kite-shaped quadrilateral KETE has the following known measures and properties:
- The diagram is labeled with points K, E, T, and E.
- The internal angles and lengths at various points are also labeled.
- Included in the diagram is a right triangle KMET within the kite, with M at the intersection of the diagonals.
**Label Information:**
1. Angle K = 72°
2. Angle T = 66°
3. The measures for angles 1, 2, and 3 within the kite are not provided and need to be determined.
**Properties of a Kite:**
1. Two pairs of adjacent sides are equal.
2. Diagonals are perpendicular.
3. One pair of opposite angles are equal (the angles between unequal sides).
**Task:**
Identify the missing measures for angles labeled as 1, 2, and 3 in the diagram, using the properties of a kite.
---
For a complete understanding and to solve for the missing measures, follow these steps on your educational website's interactive geometry tool or use the provided worksheet:
1. **Identify Angles 1, 2, and 3:**
- Use the known outer angles (72°, 66°) and the fact that the diagonals of a kite are perpendicular to find the values of interior angles.
- Remember, the diagonals of a kite bisect these interior angles.
2. **Apply Angle Properties:**
- Use the property where the sum of the internal angles in any quadrilateral is 360°. This will help to find the missing angles once two of the angles are known (the given 72° and 66°).
3. **Step-by-Step Calculation:**
- Calculate the right angles where the diagonals intersect (90° each).
- Determine the remaining angles using subtraction from total internal angles (360°).

**Educational Content: Angle Identification in a Triangle**
In this exercise, you are asked to determine the measures of angles within a specific triangle. Below is an illustration of our triangle with some of its angles provided. Your task is to find the measure of the remaining angles.
### Diagram Explanation:
- The triangle shown has three angles with the following given measures:
- One angle is marked as 72°.
- Another angle is marked as 66°.
- The triangle is labeled in such a way that you need to calculate the unknown angles and fill in the boxes corresponding to angles ∠1, ∠2, and ∠3.
### Questions:
Given the measures in the diagram, complete the following:
- \( m∠1 = \_\_\_\_ \)
- \( m∠2 = \_\_\_\_ \)
- \( m∠3 = \_\_\_\_ \)
### Solving Strategy:
To find the measure of an unknown angle in a triangle, remember that the sum of the interior angles of any triangle is always 180°. Therefore, you can calculate the unknown angle by summing up the measures of the known angles and subtracting from 180°.
**Note:** This particular problem focuses on internal calculations to determine missing angle measures.
