An angle bisector always creates two acute angles. find a counterexample to show that the conjecture is false.
sweet-ann [11.9K]
An acute angle is an angle that is less than 90°. An angle bisector is a ray drawn along an angle that bisects it into two equal and adjacent parts. Now, if the total angle is, say 270°, which is more than a half circle, it would result to two 135-degree angles. In this case, the angle is no longer acute, but obtuse.

21.) A rectangle has an area of 36 square units. As the length and width change, what do you know about their
natima [27]

Answer:

the length and the width are inversely proportional to each other (l=\frac{36}{w} or w=\frac{36}{l})

Step-by-step explanation:

Let

l units = length of the rectangle,

w units = width of the rectangle.

The area of the rectangle is

\text{Area}=\text{Length}\cdot \text{Width}

A rectangle has an area of 36 square units, so

l\cdot w=36

Complete the table with some values of l and w that fit the previous formula:

\begin{array}{ccc}\text{Length}&\text{Width}&\text{Area}\\ \\36&1&36\cdot 1=36\ un^2.\\18&2&18\cdot 2=36 \ un^2.\\12&3&12\cdot 3=36\ un^2.\\ 9&4&9\cdot 4=36\ un^2.\\l&w&l\cdot w=36 \ un^2.\end{array}

As you can see, the length and the width are inversely proportional to each other (l=\frac{36}{w} or w=\frac{36}{l})
