A triangle has sides of length 7 cm, 24 cm, and 25 cm. Verify if it is a right triangle and calculate its area.
This combination of measurements invites attention—common in geometry education and design inspiration. But is this triangle truly right-angled? And what does its area reveal? People curious about shapes, learning math, or exploring design fundamentals often explore these questions. Beyond curiosity, understanding right triangles supports fields like architecture, navigation, and digital graphics. More recently, this specific 7-24-25 triangle has gained visibility online, connecting learners, educators, and professionals seeking clear, reliable information. Right triangles follow a fundamental rule: the square of the longest side equals the sum of the squares of the other two sides. Here, 25 cm is the longest side, so compute 7² + 24² and compare.
49 + 576 = 625, which matches 25². This confirms the triangle is indeed a right triangle, validating its use in practical applications like construction angles or visual design proportions. To calculate the area, apply the standard formula for right triangles: one half the product of the two shorter sides.
Area = ½ × base × height = ½ × 7 cm × 24 cm = 84 cm².
This result gives a clear, tangible understanding of space within the triangle—important for education, engineering, or creative work relying on geometric accuracy. Beyond verification, the 7-24-25 triangle appears in various real-world contexts. As a right triangle, it supports trusses in building frameworks, guides navigation via trigonometric calculations, and inspires visual design layouts emphasizing balance and proportion. Its predictable shape enables precision in projects from model-making to digital modeling.
