The lengths of the two sides are 4cm and 5cm. What is the square of the length of the third side if the triangle is a right triangle I've only worked out one answer. Let's take a look at your department

The lengths of the two sides are 4cm and 5cm. What is the square of the length of the third side if the triangle is a right triangle I've only worked out one answer. Let's take a look at your department

There are two cases
1. 5cm is a hypotenuse, then according to Pythagorean theorem, 5-4 square = 3 square, that is, the square of the third side length is 9
2. 4cm and 5cm are right angle sides. Then the third side square = 4 square + 5 square = 41

The length of a right triangle is 3cm, 4cm and 5cm respectively. What is the height of the hypotenuse of the right triangle?

Height = 3 × 4 △ 5 = 2.4cm

Cut out the largest triangle from a piece of square paper. Its area is 18 square centimeters. How many square centimeters is the square

Subtract along the diagonal of the square to get two triangles with the largest area
Then the square area is 2 times the triangle area = 36 square centimeters

A piece of rectangular paper with an area of 100cm2. Cut it into two identical triangles with an area of 100cm2______ cm2．

A: the area of each triangle is 50 square centimeters

Two isosceles right triangles of equal area can form a square______ ．

Two isosceles right triangles of equal area are exactly the same and can form a square

Use two isosceles right triangles with an area of 8 square centimeters to form a square. What's the area of the square?

Use two isosceles right triangles with an area of 8 square centimeters to form a square. The area of the square is 8 + 8 = 16 square centimeters

In the handicraft class, Mr. Tang asked the students to cut an isosceles right triangle (as shown in the figure) from one corner of a rectangular paper. What is the area of the remaining part?

15 × 11 - (11-3) × (11-3) △ 2, = 165-8 × 8 △ 2, = 165-32 = 133 (square centimeter). A: the area of the rest is 133 square centimeter

Rectangular paper cut out an isosceles triangle, the isosceles triangle into two right triangles, two triangles spell convex quadrilateral, there are several
Want a picture ~ ~ ~ don't rush to explain ~ ~ ~!

There are four. You can try two triangular plates with 60 ° angle

As shown in the figure, fold a piece of rectangular paper along the diagonal. The overlapping part is an isosceles triangle. If the length of the rectangle is 8cm and the width is 6cm, then the waist length of the isosceles triangle is 6cm______ ．

∫ ab ‖ CD, ∫ DCA = ∠ cab, ∫ cab = ∠ fac, ∫ DCA = ∠ fac, ∫ AF = CF, ∫ Fe = 8-cf, ∫ Da = 6, ∫ 62 + (8-cf) 2 = CF2, ∫ CF = 254cm

There is a right triangle, right sides are 6 and 8, in the right triangle to make a square, square area

Draw a picture, let the square side length x, then according to the proportion of similar triangle sides equal, (8-x) / x = x / (6-x), then calculate the value of X, square area X, even out, the results of their own calculation oh
