Weekly Flashcardizz - Q2 - Week 9 - Benchmark Review

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the corresponding angle to \( \angle C \) in triangle \( \Delta ABC \cong \Delta NML \)?

Back

The corresponding angle to \( \angle C \) is \( \angle L \).

Front

How do you find the distance between two points on a coordinate plane?

Back

To find the distance between two points \((x_1, y_1)\) and \((x_2, y_2)\), use the distance formula: \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \).

Front

What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, \(|-5| = 5\).

Front

What is the result of dividing two negative numbers?

Back

Dividing two negative numbers results in a positive number. For example, \((-25) \div (-5) = 5\).

Front

What is the value of \(|-5| + 8?

Back

The value of \(|-5| + 8\) is 13.

Front

What does the symbol '>' mean in mathematics?

Back

The symbol '>' means 'greater than'. For example, if \( U > Y \), then U is greater than Y.

Front

How do you evaluate an expression with absolute values?

Back

To evaluate an expression with absolute values, first find the absolute value of the number, then perform the other operations. For example, in \(|-5| + 8\), first find \(|-5| = 5\), then add 8 to get 13.

Front

What is the significance of corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal, which helps in proving that two triangles are congruent.

Front

What is the formula for calculating the distance between two points on a number line?

Back

The distance between two points \( a \) and \( b \) on a number line is given by \( |a - b| \).
