Question

day 4

1. color the shapes that have no vertices.

1. how many vertices?

1. draw a shape that has more than four sides and four vertices.

Explanation:

Question 1:

Step1: Recall vertex definition

A vertex is a corner where two or more edges meet. Circles have no straight edges, so no vertices.

Step2: Identify shapes with no vertices

Among the shapes (triangle, rectangle, circle, triangle, triangle), the circle has no vertices. So color the circle.

Step1: Recall octagon properties

A regular octagon has 8 sides, and each vertex is where two sides meet.

Step2: Count vertices of octagon

An octagon (8 - sided polygon) has 8 vertices.

Step1: Recall shape properties

A shape with more than 4 sides (so at least 5 sides) and 4 vertices? Wait, no—wait, a vertex is where sides meet. Wait, a shape with 4 vertices must have 4 sides (a quadrilateral) has 4 vertices. But the problem says "more than four sides and four vertices"—this is a bit confusing. Wait, maybe a typo? Wait, no—wait, a shape with 4 vertices has 4 sides (since each vertex connects two sides, and for a simple polygon, number of sides = number of vertices). Wait, maybe the problem means more than four sides (so at least 5 sides) but that would mean at least 5 vertices. Wait, maybe the problem is misphrased. But if we consider a shape with 4 vertices (so 4 sides) but "more than four sides"—no. Wait, maybe a shape like a quadrilateral with a "dent" but no, that's still 4 vertices. Wait, maybe the problem wants a shape with more than four sides (so 5 or more) but the user might have made a mistake. Wait, no—wait, maybe the problem is to draw a shape with more than four sides (so 5 + sides) and four vertices? That's impossible for a simple polygon. Wait, maybe it's a typo and meant more than four vertices? If we assume that, a pentagon has 5 sides and 5 vertices. But if we strictly follow "more than four sides (so ≥5 sides) and four vertices"—that's impossible. But maybe the problem meant more than four sides (so 5 +) and four vertices is a mistake, and it's more than four vertices. So draw a pentagon (5 sides, 5 vertices) or hexagon (6 sides, 6 vertices), etc.

Answer:

Color the circle (the third shape from the left).
