Let’s go through each row of the table and match the word with its correct definition and picture. We’ll do this one by one, carefully checking what each term means and which image fits best.

---

1. plane shape

Definition: “a shape on a flat surface that is formed by curves, line segments, or both”

Look at the pictures in the first row — we see circle, square, triangle, rectangle, rhombus, parallelogram. All of these are flat shapes made from lines or curves. So this matches perfectly.

Correct as shown.

---

2. point

Definition: “an exact position or location”

The picture shows just a dot (•). That’s exactly what a point is — no size, just a spot.

Correct as shown.

---

3. line

Definition: “is straight, *continues in both directions*, *does not end*”

The picture shows a straight line with arrows on both ends → ← meaning it goes forever in both directions.

Correct as shown.

---

4. line segment

Definition: “is straight, *is part of a line*, *has 2 points called endpoints*”

The picture shows a straight line with two dots at the ends — those are the endpoints. It doesn’t have arrows, so it stops at both ends.

Correct as shown.

---

5. ray

Definition: “is straight, *is part of a line*, *has 1 endpoint*, *continues in one direction*”

The picture shows a line with one dot (endpoint) on the left and an arrow on the right → meaning it starts at the dot and goes forever to the right.

Correct as shown.

---

6. angle

Definition: “is formed by 2 rays that share the same endpoint”

The picture shows two rays starting from the same point (the vertex), going off in different directions — that’s an angle!

Correct as shown.

---

7. vertex / vertices

Definition: “A vertex is the shared endpoint of an angle (a corner). More than 1 vertex is called vertices.”

The picture shows an angle with a curved mark near the corner — that’s highlighting the vertex. Even though only one angle is drawn, the definition explains that “vertex” is singular and “vertices” is plural.

Correct as shown.

---

All rows are correctly matched! The table is already complete and accurate.

Final Answer:
The table is correctly filled out — each word matches its definition and picture.
