CHECK THEN TELL ME if im right!!
An equilateral triangle is also called an equiangular triangle. All 3 sides are congruent. ( the same length)
A triangle which has all three of its sides equal in length.

The French Revolution, if anything, was the most momentous event of the 18th century, even grander than the American Revolution. Its design, the causes, the results, and the ideology are so hard to perfectly pin down, so much so that there are many, many different schools of thought on it. There is classic historiography (Aulard, Lefebrves, Mathiez, etc.). There are the liberal
The person and his shadow form a triangle. The tree and its shadow also form a triangle. The triangles are similar triangles, so the lengths of corresponding sides are proportional.
Let the unknown tree height be h.
(person's height)/(person's shadow) = (tree height)/(tree's shadow)
(75 in.)/(48 in.) = h/(38 ft)
(25)/(16) = h/(38 ft)
16h = 25 * 38 ft
16h = 950 ft
h = 59.375 ft
h = 59.38 ft
24/6 = 4
36/9 = 4
<UTV = <LTM
So triangle TUV is similar to triangle TLM by SAS
Answer is B.
Similar. SAS similarity; TLM
Equilateral triangle: all sides are equal lengths, all angles are equal too
Scalene triangle: has three different sides, all angles are different
Isosceles triangle: 2 sides are equal, one isn’t, 2 angles are the same, one is different
Acute triangle: angles are less than 90 degrees
Obtuse triangle: angles are larger than 90 degrees
Right triangle: angle forms a 90 degree angle
Those are the triangles 🙂
Another term for an equilateral triangle in geometry is equiangular or a regular triangle
x = 7
According to the midline theorem, a segment joining the midpoints of two sides of a triangle is one half the length of the third side, so
2x - 6 = 8 ( add 6 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
just by using similarity of triangles we can deduce that (2x-6) is half of 16
OR you can get it by applying Mid point theorem also.
so 2x-6= 16/2
Area of the shaded region = area of outer right angle triangle - area of the inner right angle triangle
= 1/2×34×39 - 1/2× 18×21 sq inches
= 663 - 189 sq inches
= 474sq inches
