Given rectangle ABCD, ab = 16, BC = 17
In this way, three kinds of shear methods are used to obtain the qualified △ AEF
1. AE = AF = 10 (E on AB, f on AD)
2, AF = 10, de = root 51 (F on ad, E on CD)
3. AE = 10, BF = 8 (E on AB, f on BC)

The length of the rectangular paper is 20cm and the width is 8cm. Cut an isosceles triangle with the waist length of 10cm from the top so that one vertex is on one side of the rectangle and the other two vertices are on the opposite side. Calculate the bottom length of the isosceles triangle?

As shown in the figure, according to the Pythagorean theorem, be = AE2 − AB2 = 102 − 82 = 6cm, passing through point E as eg ⊥ ad to g, then the quadrilateral abeg is a rectangle, ≁ Ag = be = 6cm, ≁ AF = 2ag = 2 × 6 = 12cm, that is, the length of the bottom edge of the cut isosceles triangle is 12cm

How many isosceles right angle triangles with waist length of 2cm can be cut out at most on a 15cm long and 6cm wide rectangular cardboard?

On the rectangular paperboard, the line that can be cut 2 cm long is: 15 △ 2 = 7 (strips) 1 (CM), on the rectangular paperboard, the line segment that can be cut 2 cm in width is: 6 △ 2 = 3 (strip), the number of small squares that can be cut is: 7 × 3 = 21 (piece), the maximum number of isosceles right angle triangles that can be cut 2 cm in waist length

How many isosceles right angle triangles with waist length of 2cm can be cut out at most on a 15cm long and 6cm wide rectangular cardboard?

On the rectangular paperboard, the line that can be cut 2 cm long is: 15 △ 2 = 7 (strips) 1 (CM), on the rectangular paperboard, the line segments that can be cut 2 cm in width are: 6 △ 2 = 3 (strips), the number of small squares that can be cut is: 7 × 3 = 21 (pieces), the number of isosceles right angle triangles that can be cut up to 2 cm in waist length is: 21 × 2 = 42 (pieces). A: the number of isosceles right angle triangles that can be cut up to 2 cm in waist length is 42 (pieces)

In the labor skill class, the teacher asked the students to write a picture with a length of 17cm and a width of 16 & nbsp; Cut an isosceles triangle with the waist length of 10cm from the rectangular cardboard (one vertex of the isosceles triangle should coincide with one vertex of the rectangle, and the other two vertices should be on the edge of the rectangle). Please help students design different types of isosceles triangles that you think meet the conditions (draw the schematic diagram in the following rectangles respectively) and calculate the isosceles cut respectively The area of the waist triangle

As shown in the figure: (1) 10 × 10 △ 2 = 50cm2; (2) AE = 16-10 = 6cm, AF = 102 − 62 = 8cm, 10 × 8 △ 2 = 40cm2; (3) CF = 17-10 = 7cm, EC = 102 − 72 = 51cm, 10 × 51 △ 2 = 551cm2

The base angle of isosceles triangle is 15 ° and the waist length is 2cm. What is the area of this triangle?

The base angle of an isosceles triangle is 15 degrees
The external angle of vertex angle = 30 degrees
The waist length is 2cm
The height on the waist = 2 × 189; = 1cm
The area of triangle is 2 × 1 △ 2 = 1 cm and 178;

An isosceles triangle has a base angle of 75 degrees and a waist length of 4cm. Then the height of the waist is cm and the area of the triangle is

The vertex angle is 30 degrees, the height of the waist is 30 degrees, the opposite side is just half of the waist, 2cm, and the area of the triangle is 4 square centimeters

If the perimeter of isosceles triangle is 28cm and the ratio of two sides is 2:3, then the length of the bottom is 2______ ．

① If the ratio of two sides is 2:3, if the waist length is 2x, the length of the bottom side is 3x, then the series equation is 2x + 2x + 3x = 28, ∧ x = 4, ∧ 3x = 12; if the ratio of two sides is 2:3, if the waist length is 3x, the length of the bottom side is 2x, then the series equation is 3x + 3x + 2x = 28, ∧ x = 72, ∧ 2x = 7. So the answer is 12 or 7

An isosceles triangle board is 7-8 meters long on one side and 3-5 meters long on the other side. What is the perimeter of this board?

If 7 / 8 is the bottom, 3 / 5 is the waist, 3 / 5 + 3 / 5 = 6 / 5 ＞ 7 / 8, in line with the meaning of the question, the circumference is: 3 / 5 * 2 + 7 / 8 = 83 / 40
If 3 / 5 is the bottom, 7 / 8 is the waist, 7 / 8 + 7 / 8 = 14 / 8 ＞ 3 / 5, the circumference is: 7 / 8 * 2 + 3 / 5 = 47 / 20

The circumference of an isosceles triangle is 27 cm. The middle line of a waist divides the triangle into two triangles with a circumference difference of 6 cm, and calculates the length of each side of the isosceles triangle
Like the title,

Waist: X
x-(27-2x)=6
3x=33
x=11
The length of each side of isosceles triangle 11,11,5
(27-2x)-x=6
3x=21
x=7
The length of each side of isosceles triangle is 7,7,13
