180 degrees.
Acute triangle - all of the angles are less than a right angle (90°).Scalene triangle - none of the sides or angles are congruent. It can be shown that if no two angles are the same, then no two sides are the same using the Law of Sines and Law of Cosines.
rhombus
An isometric triangle is a 3 dimensional triangle shown on a flat surface or in 2 dimensions.

A triangle has 3 line segments
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
The length depends on the triangle or the quadrilateral. Normally the figure is shown with one side horizontal, which is called the base. In a triangle, the altitude is the the line from the third vertex down to the base (or the extended base) and which is perpendicular to the base. In a quadrilateral, it is similar, but is the longer of the two lines from the two vertices that are not on the base itself. maximum length of a line perpendicular to the base that

rhombus
Which of the following is a valid reason why the quadrilateral shown below is a parallelogram?
A quadrilateral is any four sided plane figure. A parallelogram has the two opposite sides parallel. This makes to two opposite sides of equal length. The figure does not necessarily have right angles. A quadrilateral can be;- square, rectangle, rhombus, parallelogram, (a)symmetric trapezium, a kite, or an irregular shape/form.
A golden triangle is an isosceles triangle such that bisecting one of the equal angles produces a new triangle that is similar to the original. It can be shown that the original triangle must be 72-72-36 degrees. Using trigonometry, or the similarity, it can be shown that the long sides were (1+Φ) times the shorter, where Φ is the golden ratio. So with the shorter side being 7 inches, the longer were 18.3 inches, approx.
To show that triangles ABC and DEF are congruent by the AAS (Angle-Angle-Side) theorem, you need to establish that two angles and the non-included side of one triangle are congruent to the corresponding two angles and the non-included side of the other triangle. If you have already shown two angles congruent, you would need to prove that one of the sides opposite one of those angles in triangle ABC is congruent to the corresponding side in triangle DEF. This additional information will complete the criteria for applying the AAS theorem.
the triangle has the greater perimeter
The Angle-Angle-Side (AAS) Congruence Theorem can be proven using two main reasons: first, if two angles of one triangle are congruent to two angles of another triangle, the third angles must also be congruent due to the triangle sum theorem. Second, with an included side between these two angles, the two triangles can be shown to be congruent using the Side-Angle-Side (SAS) criterion, as both triangles share the same side and have two pairs of congruent angles.
