Hello do you think you can help me with this
**Problem 2: Rotation of Triangle**

- Task: Rotate Triangle B 90 degrees clockwise using point R as the center of rotation.
- Instructions: In the image, identify and write the measure of each angle within the triangle.

**Diagram Details:**
  
- The triangle is placed on a grid made up of equilateral triangles.
- The initial orientation of the triangle shows angles labeled as 30°, 60°, and a right angle (90°).
- Point R is marked as the center of rotation near the right angle of the triangle.

**Problem 3: Reflection of Pentagon**

- Task: Reflect Pentagon C across line ℓ.

**Diagram Details:**

- The diagram shows a grid with lines forming squares.
- Line ℓ is marked vertically on the grid.
- A right angle of 90° and an angle of 150° are shown in the diagram, indicating parts of a shape adjacent to line ℓ.

These exercises involve geometric transformations—rotation and reflection—emphasizing understanding of angles and spatial reasoning.
