Explanation

The points form a scalene triangle:

Calculate the distances AB, BC, and AC. If all sides are unequal, it's a scalene triangle.

AB = √((1 - (-4))² + (4 - (-2))²) = √(5² + 6²) = √61

BC = √((6 - 1)² + (11 - 4)²) = √(5² + 7²) = √74

AC = √((6 - (-4))² + (11 - (-2))²) = √(10² + 13²) = √269

All sides are unequal (√61 ≠ √74 ≠ √269), so the points form a scalene triangle.

Explanation

The pith is the central part of the stem, mainly used for storage of nutrients and water.

It is surrounded by vascular tissues that transport water and nutrients throughout the plant.

Explanation

Problem-Based Learning (PBL) presents students with real-world, open-ended problems without a clear solution.

It encourages group collaboration, critical thinking, and self-directed learning to find solutions.

Explanation

The correct order of adjectives in English typically follows: Determiner + Opinion + Size + Age + Shape + Color + Noun.

"That (determiner) small (size) new (age) square (shape) red (color) bag (noun)" follows this standard adjective order.

Explanation

My cousin will visit us soon.

Common gender words can refer to either male or female (e.g., cousin).

Explanation

The largest portion of Earth's freshwater is stored in glaciers and permanent ice sheets.

Lakes, streams, and underground water hold smaller percentages compared to ice sheets.

Explanation

In large numbers, commas are placed after every three digits starting from the right.

For example, 1,000 and 10,000,000 have commas after every three digits.

Explanation

If a² + b² < c², then angle C is greater than 90°, making it an obtuse triangle.

This follows from the converse of the Pythagorean Theorem.

Explanation

In C language, each statement ends with a semicolon (;) to indicate the end of an instruction.

This helps the compiler understand where one statement ends and the next begins.

Explanation

Optical disks like CDs and DVDs store data in a spiral track that starts from the innermost part and moves outward.

This spiral path allows continuous reading of data as the disk spins.
