Looking at shapes | 1st grade, 2nd grade Math Worksheet | GreatSchools - Free Printable

Problem Overview:

The task involves identifying the names of various 2-dimensional shapes, counting their sides, and counting their corners (vertices). The image provides a grid with different shapes, and the goal is to fill in the blanks for each shape.

Solution Approach:

1. Identify the Shape: Recognize the name of each geometric shape.
2. Count the Sides: Determine how many straight edges the shape has.
3. Count the Corners (Vertices): Identify how many points where the sides meet.

Let's solve this step by step for each shape.
