triangle
Classification
by angle
Acute triangle: All three angles are acute. Right triangle: One angle is a right angle. The two acute angles of an isosceles triangle are 45 degrees each, and it has an axis of symmetry. Obtuse triangle: One angle is obtuse.
Divide by sides
Scalene triangle: The three sides are not equal in length. Isosceles triangle: has two sides of equal length; two equal base angles; and an axis of symmetry. Equilateral triangle: All three sides are equal in length; all three interior angles are 60 degrees; there are three axes of symmetry.
feature
A figure bounded by three line segments. The sum of interior angles is 180 degrees. Triangles have stability. A triangle has three heights.
Calculation formula
s=ah➗2
round
feature
A curved figure on a plane. The point in the center of the circle is called the center of the circle. Generally represented by the letter o. Radius: The line segment connecting the center of the circle and any point on the circle is called the radius. Generally expressed by r. In the same circle, there are countless radii, and the length of each radius is equal. The line segment that passes through the center of a circle and has both ends on the circle is called the diameter. Generally represented by d. There are countless diameters in the same circle, and all diameters are equal. In the same circle, the diameter is equal to the length of the two radii, that is, d=2r. The size of the circle is determined by the radius. A circle has countless axes of symmetry.
Art style
Separate the two legs of the compass and determine the distance (i.e. radius) between the two legs; Fix one foot with the tip of the needle at one point (i.e., the center of the circle); Rotate one foot with the pencil tip in one circle to draw a circle.
perimeter
The length of the curve surrounding a circle is called the circumference of the circle. The ratio of a circle's circumference to its diameter is called pi. Represented by letters.
area
The size of the plane occupied by a circle is called the area of the circle.
Calculation formula
d=2r r=d/2 c=d c=2r s=r2
Parallelogram
feature
A quadrilateral with two sets of opposite sides that are parallel
Opposite sides are parallel and equal. Opposite angles are congruent and the sum of the measures of two adjacent angles is 180 degrees. Parallelograms are easily deformed.
Calculation formula
s=ah
Axisymmetric graphics
If a figure is folded in half along a straight line and the figures on both sides can completely overlap, the figure is an axially symmetrical figure. The line along which the crease is located is called the axis of symmetry. A square has 4 axes of symmetry and a rectangle has 2 axes of symmetry. An isosceles triangle has 2 axes of symmetry and an equilateral triangle has 3 axes of symmetry. An isosceles trapezoid has one axis of symmetry, and a circle has countless axes of symmetry. A rhombus has four axes of symmetry and a sector has one axis of symmetry.
square
feature
A quadrilateral with four equal sides and four right angles. There are 4 axes of symmetry.
A square is a special rectangle, a special parallelogram
Calculation formula
c=4a
s=2a
rectangle
feature
Subtopic: A quadrilateral with equal opposite sides and four right angles. There are two axes of symmetry.
Calculation formula
c=2(a b)
s=ab
is a special parallelogram
trapezoid
feature
There is only a set of parallel quadrilaterals. The midline is equal to half the sum of the upper and lower bases. An isosceles trapezoid has an axis of symmetry.
Calculation formula
s=(a b)h➗2
a=2s➗h-b
b=2s➗h-a
