AngleRight vs Xplore Hiroshima

AngleRight solves triangles and parallelograms and draws them to scale as you type. Enter what you know and every side, angle, height and area appears instantly, with clear step-by-step working. RIGHT TRIANGLES • Right angle at B: solve from two legs, a leg and the hypotenuse, a leg and an angle, the hypotenuse and an angle, or the area and a leg • Pythagoras, sine, cosine and tangent shown step by step ANY TRIANGLE • SSS, SAS, ASA, AAS and SSA • The ambiguous SSA case shows both possible triangles, or explains why none exists • Area, perimeter, heights, medians, inradius and circumradius • Tells you whether a triangle is acute, right or obtuse, and scalene, isosceles or equilateral PARALLELOGRAMS • Solve from two sides and an angle, two sides and the height, two sides and a diagonal, the base with height and angle, or both diagonals • Height, diagonals, area and perimeter, and whether it is a square, rectangle or rhombus PROTRACTOR AND TILT LEVEL • Drag two arms to measure any angle, with supplement and reflex angles • Tilt level: lay your iPhone on a surface or hold its edge against a slope DRAW • Drag the corners of a triangle or four-sided shape on a grid and watch the measurements update live • Snap to grid, and one tap to make a right angle, a parallelogram or a rectangle DESIGNED FOR iPHONE AND iPAD • Four themes — Pearl, Midnight, Royal Gold and Sand — plus Auto for Light and Dark Mode • Landscape layout with the drawing beside the controls • Degrees or radians, 0 to 4 decimal places • Optional inscribed and circumscribed circles and heights on the drawings • Share your results as text • A formula guide covering Pythagoras, SOH CAH TOA, the sine and cosine rules, area and more PRIVATE BY DESIGN No account, no ads, no tracking and no internet connection needed.

On August 6, 1945, the first atomic bomb ever used in war was dropped on Hiroshima, Japan, ushering in the nuclear age. Within 10 seconds, blistering heat, blast winds, and deadly radiation reduced a once vibrant and bustling city to rubble and ash. Hiroshima's atomic bomb survivors, or in Japanese, hibakusha, have been working tirelessly for 75 years to ensure that what happened to them will never happen again, anywhere on Earth. What did the people living in Hiroshima experience? How is Hiroshima's past and present relevant to our own lives? And how can the stories of hibakusha inspire us to create a more sustainable and peaceful future? During this tour, local guides Mary (American), and Haruki (Japanese) will introduce Hiroshima Peace Park, formerly Nakajima District, one of Hiroshima's busiest downtown centers and the target of the atomic bombing. You will see video footage from the day, toggle between maps of past and present Hiroshima, interact with 3D models of Little Boy, the A-bomb fireball, and the Atomic Bomb Dome, and hear the testimonies of hibakusha accompanied by art they created to convey their experiences. Stops include the Atomic Bomb Dome and Rest House, two A-bombed buildings that remain in the Peace Park even today, the hypocenter of the atomic bombing, the Cenotaph for the A-bomb Victims, and the Sadako Sasaki inspired Children's Peace Monument.
