1.[tex]True[/tex]
[tex]Explanation[/tex]
Triangles are polygons with three sides, so any polygon with three sides is called a triangle.
2.[tex]False[/tex]
[tex]Explanation[/tex]
You probably know that the sum of any triangle's angles is always 180 degrees. In an acute triangle, the sum of any two angles is always greater than 90 degrees. This is because in an acute triangle, no one angle can be greater than 89.999 degrees (and yes, those nines could go on forever)
3.[tex]True[/tex]
[tex]Explanation[/tex]
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.
4.[tex]True[/tex]
[tex]Explanation[/tex]
You can also use your knowledge of triangles as a way to understand why the sum of the interior angles of any quadrilateral is 360°. Any quadrilateral can be divided into two triangles as shown in the images below
5..[tex]True[/tex]
[tex]Explanation[/tex]
Yes. Every parallelogram with 4 equal sides must be a rhombus. Additionally if the parallelogram has 4 equal sides and a right angle, it must be a square, but every square is still a rhombus.
