Printable Grade 2 math worksheet designed to teach students how to identify right angles in different geometric shapes.

Let’s go step by step to find which shapes have right angles.

A right angle is exactly 90 degrees — like the corner of a square or rectangle, or the shape of an “L”.

We’ll look at each shape one by one:

1. Triangle (first row, left) – This looks like an equilateral triangle. All its angles are less than 90° → ✘ No right angle.

2. Square with red mark (first row, middle) – The red “L” symbol means this corner is marked as a right angle → ✔ Yes!

3. Hexagon (first row, right) – Regular hexagons have angles of 120° → ✘ No right angle.

4. Circle (second row, left) – Circles have no corners or angles → ✘ No.

5. Arrow (second row, middle) – Look at the back end of the arrow: it has two straight lines meeting at 90° on both top and bottom → ✔ Yes! (Actually, it has *two* right angles.)

6. L-shape (second row, right) – This is literally shaped like an “L” — that’s the classic right angle symbol → ✔ Yes!

7. Semicircle (third row, middle) – It has a curved side and a straight base. Where the curve meets the straight line? Not a sharp corner → ✘ No right angle.

8. Trapezoid (bottom row, left) – Only one pair of sides parallel. Angles are not 90° unless specified → ✘ No.

9. Diamond / Rhombus (bottom row, middle) – Looks like a tilted square. But unless it’s a square, its angles aren’t 90°. In this drawing, it appears to be a rhombus with non-right angles → ✘ Probably not. *(Note: If it were a square rotated, it would still have right angles — but visually, this looks more like a typical rhombus with acute/obtuse angles. Since no marking, we assume no right angles.)*

Wait — let’s double-check the diamond. Actually, in many Grade 2 worksheets, if it’s drawn as a perfect square rotated 45°, it still has 4 right angles. But here, looking closely, the sides are equal but the angles don’t appear to be 90° — they’re sharper and wider. So safer to say ✘ no right angle unless marked.

But hold on — actually, in standard geometry, a rhombus does NOT necessarily have right angles. Only squares do. Since this isn’t labeled as a square, and doesn’t have right-angle marks, we’ll say ✘.

10. Shape with curved corners (bottom row, right) – It’s like a square but with rounded corners → ✘ No sharp 90° angles.

So, summarizing the ones that DO have right angles:

- Square (with red mark)
- Arrow (has 2 right angles at the tail)
- L-shape

That’s three shapes.

Final check: Did we miss any?

What about the trapezoid? Sometimes right trapezoids exist — but this one doesn’t look like it. The slanted side suggests non-right angles.

The semicircle? No.

Circle? No.

Hexagon? No.

Triangle? No.

Curved-corner shape? No.

Diamond? We decided no.

✔ Confirmed: Square, Arrow, L-shape.
