Does an equilateral triangle have 3 angles?
yes all triangles have three angles the word meaning tri
How many obtuse angles in a squre?
None... All 4 angles are right angles (right angle means 90 degrees), meaning the angles are neither obtuse, nor acute.
What is the meaning of alternate exterior angles?
When a line transverses parallel lines the alternate exterior angles of that line are equal
What is the meaning of the protractor?
A semicircular instrument for measuring and constructing angles.
What is the meaning of vertical angles in geometry?
They are angles formed when two straight lines intersect: they are on opposite sides of the point of intersection.
What shape has 11 sides and 11 angles?
A shape with 11 sides and 11 angles is called a hendecagon or undecagon. The term "hendecagon" comes from the Greek words "hendeka," meaning eleven, and "gonia," meaning angle. This polygon can be regular, where all sides and angles are equal, or irregular, with varying side lengths and angles.
What is the meaning of degrees and 'in sine laws?
It is one unit of measure of angles.
How are figures related by a translation?
they are not rotated meaning that their angles are in the same place
Are all four angles in a rhombus congruent?
No, not all four angles in a rhombus are congruent. A rhombus has opposite angles that are congruent, and the adjacent angles are supplementary, meaning they add up to 180 degrees. Therefore, while opposite angles are equal, the four angles are not necessarily all the same. In fact, a rhombus can have two acute angles and two obtuse angles.
If a quadrilateral is a parallelogram then consecutive angles are complementary?
Consecutive angles in a parallelogram will not be complementary. Complementary would mean the angles would add up to 90 degrees. Consecutive angles add up to 180 degrees, meaning they are supplementary.
What has 12 sids and 12 angles?
A shape with 12 sides and 12 angles is known as a dodecagon. In geometry, a dodecagon can be regular, meaning all sides and angles are equal, or irregular, where the sides and angles can vary. Regular dodecagons have internal angles measuring 150 degrees each.
What is an obtuse vertical angle?
Angles larger than a right angle and smaller than two right angles (between 90° and 180°) are called obtuse angles("obtuse" meaning "blunt").
