Explanation

Widow refers to a woman whose spouse has died, while bachelor refers to an unmarried man, so they are not exact opposites.

Uncle–Aunt, King–Queen, Mister–Miss are gender opposites or counterparts.

Explanation

To determine the nature of the triangle formed by points A(-2, 0), B(2, 0), and C(0, √12), let's calculate the distances between each pair of points.

Step 1: Calculate the distance AB

AB = √((2 - (-2))² + (0 - 0)²) = √(4²) = √16 = 4

Step 2: Calculate the distance AC

AC = √((0 - (-2))² + (√12 - 0)²) = √(2² + (√12)²) = √(4 + 12) = √16 = 4

Step 3: Calculate the distance BC

BC = √((0 - 2)² + (√12 - 0)²) = √((-2)² + (√12)²) = √(4 + 12) = √16 = 4

Step 4: Determine the nature of the triangle

Since AB = AC = BC = 4, the triangle is equilateral.

Explanation

For adjectives with more than two syllables, use "more" to form the comparative.

So, "more beautiful" is correct.

Explanation

Supplementary angles are two angles whose sum is exactly 180 degrees.

They often form a straight line when placed adjacent to each other.

Explanation

Percentage = (Number of eggs used / Total number of eggs) * 100

= (8 / 64) * 100

= 0.125 * 100

= 12.5%

Explanation

Deductive Reasoning moves from general principles to specific conclusions.

Example: "All birds have feathers; a sparrow is a bird; therefore, it has feathers."

Inductive Reasoning moves from specific observations to general conclusions.

Example: "The sun rose today and yesterday; therefore, it always rises in the morning."

Explanation

The sentence "Her smile was as bright as the sun" uses the word "as" to directly compare her smile to the sun.

This is the hallmark of a simile, a figure of speech that compares two different things using "like" or "as."

Explanation

She said that she was feeling tired then.

In reported speech, present continuous "am feeling" changes to past continuous "was feeling."

"Now" changes to "then."

Explanation

A reflex angle is any angle greater than 180° but less than 360°.

215° fits this definition.

Explanation

The absolute value of a number is its distance from 0 on the number line, always positive.

So, |−13| = 13.
