Answer:
<em>3. No.</em>
<em>4. No, not necessarily.</em>
<em>5. Yes.</em>
Step-by-step explanation:
3. No. With the two triangles, she knows that one angle of each is a right angle. She does not know anything about side lengths. She cannot prove the triangles are congruent.
4. We cannot prove the triangles are congruent. With the perpendicular segments, there is a pair of congruent, right angles. Then there are two pairs of sides that are congruent, but the order is SSA, and SSA does not prove triangles congruent.
5. Using the two sets of perpendicular lines, you have two congruent, right angles. Then you have the other pair of given congruent angles. Finally, segment RT is congruent to itself. This makes AAS. the triangles are congruent.
Answer:
The regular polygon is a nonagon
Step-by-step explanation:
<u><em>The correct question is</em></u>
What is the name of the regular polygon that each interior angle measures 140ﾟ?
we know that
The formula to find the sum of the interior angles in a regular polygon is equal to
where
n is the number of sides of the regular polygon
a is the measure of each interior angle of the regular polygon
we have
substitute in the formula and solve for n
so
The regular polygon has 9 sides
therefore
The regular polygon is a nonagon
I can't see any table, is there a picture?
but something like 45x would be near the answer
