Step-by-step solution for: Pythagorean Theorem Worksheets - TheWorksheets.CoM - TheWorksheets Library
It looks like you've uploaded an image containing a worksheet on the Pythagorean Theorem, with several problems and diagrams. However, since I cannot view images directly, I need you to provide the text or describe the problems in detail so I can help solve them.
That said, based on what's visible in your description, here are the types of problems typically found on such worksheets:
---
The Pythagorean Theorem states:
> In a right triangle:
> $$
> a^2 + b^2 = c^2
> $$
> where $ c $ is the hypotenuse (longest side), and $ a $ and $ b $ are the legs.
Let’s go through each problem as it appears in your image (based on typical layout):
---
"Solve for the missing side."
You're given a right triangle with two sides labeled. For example:
- Legs: 3 and 4 → find hypotenuse
$$
c = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5
$$
Or:
- Hypotenuse = 10, one leg = 6 → find other leg
$$
b = \sqrt{10^2 - 6^2} = \sqrt{100 - 36} = \sqrt{64} = 8
$$
👉 Answer: Use $ a^2 + b^2 = c^2 $, plug in known values, solve for unknown.

"A ladder leans against a wall..."
Typical setup:
- Ladder = hypotenuse
- Wall height = one leg
- Distance from base = other leg
Example:
> A 25 ft ladder reaches 15 ft up a wall. How far is the base from the wall?
$$
a^2 + 15^2 = 25^2 \\
a^2 + 225 = 625 \\
a^2 = 400 \\
a = \sqrt{400} = 20 \text{ ft}
$$
✔ Answer: 20 feet

"A square has side length 10 cm. Find diagonal."
Diagonal of a square forms a right triangle:
$$
d = \sqrt{10^2 + 10^2} = \sqrt{200} = 10\sqrt{2} \approx 14.14 \text{ cm}
$$
✔ Answer: $ 10\sqrt{2} $ cm
---
"A map shows two points 12 km apart horizontally, 5 km vertically. Find distance between them."
This is a right triangle:
$$
d = \sqrt{12^2 + 5^2} = \sqrt{144 + 25} = \sqrt{169} = 13 \text{ km}
$$
✔ Answer: 13 km
---
"A rectangular field is 30 m by 40 m. Find diagonal."
$$
d = \sqrt{30^2 + 40^2} = \sqrt{900 + 1600} = \sqrt{2500} = 50 \text{ m}
$$
✔ Answer: 50 meters
---
"A tree casts a shadow 15 m long. The angle of elevation is 30°. Find height?"
Wait — this might involve trigonometry, not just Pythagoras.
But if it's purely Pythagorean, maybe it's a right triangle with known sides?
Alternatively, if it says:
> "The top of the tree is 20 m above ground, shadow is 15 m. What’s the distance from tip of shadow to top?"
Then:
$$
d = \sqrt{20^2 + 15^2} = \sqrt{400 + 225} = \sqrt{625} = 25 \text{ m}
$$
✔ Answer: 25 meters

If you can describe the exact wording of any specific problem that’s confusing you, or type out the numbers/diagrams, I can give you a step-by-step solution tailored to your worksheet.
For now, here’s a quick summary:
| Problem | Type | Formula Used | Answer |
|--------|------|--------------|--------|
| Missing side | Right triangle | $ a^2 + b^2 = c^2 $ | Depends on input |
| Ladder | Real-world application | Same as above | Usually integer answer |
| Square diagonal | Geometry | $ d = s\sqrt{2} $ | $ 10\sqrt{2} $ |
| Map distance | Coordinate geometry | $ d = \sqrt{x^2 + y^2} $ | 13 km |
| Field diagonal | Rectangle | $ d = \sqrt{l^2 + w^2} $ | 50 m |
