Answer:

All Triangles are closed figure polygons that have three straight sides

Step-by-step explanation:

All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.

What is the common denominator of StartFraction 1 Over a EndFraction StartFraction 1 Over b EndFraction in the complex fraction

stepladder [879]

The common denominator is 1

Given the expression:

$\frac{1/a-1/b}{1/a1/b}$

Find the LCM of the numerator to have:

$\dfrac{\frac{b-a}{ab} }{\frac{1}{a} \frac{1}{b} }$

Simplify both the numerator and the denominator to have:

$= \dfrac{\frac{b-a}{ab} }{\frac{1}{ab} }\\= \frac{b-a}{ab} \times ab\\=\frac{b-a}{1} \times 1 \\=\frac{b-a}{1}$

From the result, we can see that the common denominator is 1
